COLOUR ME HEALTHY

Different Colours can affect us in many different ways; that’s according to Verity Allen. In
her new series ‘Colour me Healthy’, Verity looks at the ways that 1 can
influence how hard we work and the choices we make. They can even change our emotions

am
and even influence how healthy we are.

‘Have you ever noticed how people always use the same colours for the same things?’ says
Verity. ‘Our toothpaste is always white or blue or maybe red. It’s never green. Why not? For
some reason we think that blue and white is clean, while we think of green products as
being a bit disgusting. It’s the 2 for businesses. We respect a company which
rJ
writes its name in blue or black, but we don’t respect one that uses pink or orange. People
who design new 3 can use these ideas to influence what we buy.’

During this four-part 4 , Verity studies eight different colours, two colours in
each programme. She meets people who work in all aspects of the colour industry, from
people who 5 food packets, to people who name the colours of lipsticks.
he

Some of the people she meets clearly have very little scientific knowledge to support their
6 , such as the American ‘Colour Doctor’ who believes that serious diseases
can be cured by the use of coloured lights. However, she also interviews real scientists who
are studying the effects of green and red lights on mice, with some surprising results.
ac

Overall, it’s an interesting show, and anyone who watches it will probably find out
something new. But because Verity is goes out of her way to be polite to everyone she
meets on the series, it’s up to the viewers to make their own decisions about how much
they should believe.

20.Paragraph VI

Paragraph I
ac

Jeremy Sanders and his colleagues at the University of Cambridge have designed and
synthesized a large cyclic "receptor" molecule, which makes one such reaction proceed
almost 60,000 times as fast as usual. The receptor is similar to another built last year by the
Te

same team (New Scientist, Science, 1 February 1992). It consists of a ring of three porphyrin
molecules linked by bridging chemical groups. Each porphyrin molecule contains a zincion
at its centre. The central cavity of the new receptor is slightly smaller than before, and the
researchers have also anchored pyridine groups to two of the zincions to act as bonding
sites.

page 10
Telegramdagi kanal: https://t.me/MULTILEVELfreeC1

Paragraph II

Sanders and his colleagues have used their receptor to speed up and control the products
of the so-called Diels-Alder reaction, a mainstay of chemical synthesis. The reaction occurs
between two molecules - a "diene", which has two carbon-carbon bonds separated by a

id
single bond, and a diene-seeking molecule, or "dienophile". In the right conditions, these
two molecules transfer the electrons involved in their double bonds from atom to atom to
form new bonds that complete a ring of six carbon atoms with a single double bond. The

sh
creation of such six-membered rings is the crucial first step in making many
pharmaceuticals and agrochemical.

Paragraph III

Some Diels-Alder reactions are too slow to be useful industrially. The researchers,

am
therefore, designed their receptor so that it would hold the diene and dienophile, via the
pyridine (Py) groups, in the right positions to react quickly. According to Sanders, the
receptor acts like a "molecular reaction vessel in which the effective concentration of
reactants can be increased dramatically, so allowing a fast reaction".

Paragraph IV
rJ
Normally, Diels-Alder reactions produce a mixture of two products. But because in the
receptor the reactants are forced into a specific orientation relative to each other, only one
of the two possible products can form.

Paragraph V
he

Sanders hopes to modify the receptor to bring together in the cavity two molecules that do
not normally react. This could lead to be the synthesis of compounds which everyday
synthetic chemistry cannot make.
ac

Paragraph VI

The receptor differs from an enzyme or other catalyst in one important respect. Only a tiny
amount of an enzyme is needed to make a reaction thousands of times faster, but large
quantities of the receptor are needed to make a significant difference to the speed of a
Te

reaction. However, Sanders is confident that in the future his team will be able to increase
the turnover or able to increase the turnover of reactants by designing new features into
the receptor. This would reduce the amount of receptor needed to speed up a reaction by a
given amount. The researchers report further details of their results in the latest issue of
Journal of the Chemical Society, Chemical Communications.

Part 4

Read the following text for questions 21-29

How bacteria invented gene editing

id
1. This week the UK Human Fertilisation and Embryology Authority okayed a proposal
to modify human embryos through gene editing. The research, which will be carried
out at the Francis Crick Institute in London, should improve our understanding of

sh
human development. It will also undoubtedly attract controversy - particularly with
claims that manipulating embryonic genomes is a first step towards designer babies.
Those concerns shouldn't be ignored. After all, gene editing of the kind that will soon
be undertaken at the Francis Crick Institute doesn't occur naturally in humans or

am
other animals.
2. It is, however, a lot more common in nature than you might think, and it's been going
on for a surprisingly long time - revelations that have challenged what biologists
thought they knew about the way evolution works. We're talking here about one
particular gene editing technique called CRISPR-Cas, or just CRISPR. It's relatively fast,
cheap and easy to edit genes with CRISPR - factors that explain why the technique
rJ
has exploded in popularity in the last few years. But CRISPR wasn't dreamed up from
scratch in a laboratory. This gene editing tool actually evolved in single-celled
microbes.
3. CRISPR went unnoticed by biologists for decades. It was only at the tail end of the
1980s that researchers studying Escherichia coli noticed that there were some odd
he

repetitive sequences at the end of one of the bacterial genes. Later, these sequences
would be named Clustered Regularly Interspaced Short Palindromic Repeats -
CRISPRs. For several years the significance of these CRISPRs was a mystery, even
when researchers noticed that they were always separated from one another by
ac

equally odd 'spacer' gene sequences.


4. Then, a little over a decade ago, scientists made an important discovery. Those
'spacer' sequences look odd because they aren't bacterial in origin. Many are actually
snippets of DNA from viruses that are known to attack bacteria. In 2005, three
Te

research groups independently reached the same conclusion: CRISPR and its
associated genetic sequences were acting as a bacterial immune system. In simple
terms, this is how it works. A bacterial cell generates special proteins from genes
associated with the CRISPR repeats (these are called CRISPR associated - Cas -
proteins). If a virus invades the cell, these Cas proteins bind to the viral DNA and help
cut out a chunk. Then, that chunk of viral DNA gets carried back to the bacterial cell's

page 12
Telegramdagi kanal: https://t.me/MULTILEVELfreeC1

genome where it is inserted - becoming a spacer. From now on, the bacterial cell can
use the spacer to recognise that particular virus and attack it more effectively.
5. These findings were a revelation. Geneticists quickly realised that the CRISPR system
effectively involves microbes deliberately editing their own genomes - suggesting the

id
system could form the basis of a brand new type of genetic engineering technology.
They worked out the mechanics of the CRISPR system and got it working in their lab
experiments. It was a breakthrough that paved the way for this week's
announcement by the HFEA. Exactly who took the key steps to turn CRISPR into a

sh
useful genetic tool is, however, the subject of a huge controversy. Perhaps that's
inevitable - credit for developing CRISPR gene editing will probably guarantee both
scientific fame and financial wealth.
6. Beyond these very important practical applications, though, there's another CRISPR

am
story. It's the account of how the discovery of CRISPR has influenced evolutionary
biology. Sometimes overlooked is the fact that it wasn't just geneticists who were
excited by CRISPR's discovery - so too were biologists. They realised CRISPR was
evidence of a completely unexpected parallel between the way humans and bacteria
fight infections. We've known for a long time that part of our immune system
"learns" about the pathogens it has seen before so it can adapt and fight infections
rJ
better in future. Vertebrate animals were thought to be the only organisms with such
a sophisticated adaptive immune system. In light of the discovery of CRISPR, it
seemed some bacteria had their own version. In fact, it turned out that lots of
bacteria have their own version. At the last count, the CRISPR adaptive immune
system was estimated to be present in about 40% of bacteria. Among the other
he

major group of single-celled microbes - the archaea - CRISPR is even more common.
It's seen in about 90% of them. If it's that common today, CRISPR must have a history
stretching back over millions - possibly even billions - of years. "It's clearly been
around for a while," says Darren Griffin at the University of Kent.
ac

7. The animal adaptive immune system, then, isn't nearly as unique as we thought. And
there's one feature of CRISPR that makes it arguably even better than our adaptive
immune system: CRISPR is heritable. When we are infected by a pathogen, our
adaptive immune system learns from the experience, making our next encounter
Te

with that pathogen less of an ordeal. This is why vaccination is so effective: it involves
priming us with a weakened version of a pathogen to train our adaptive immune
system. Your children, though, won't benefit from the wealth of experience locked
away in your adaptive immune system. They have to experience an infection - or be
vaccinated - first hand before they can learn to deal with a given pathogen.

Part 5

Architecture in Britain

From the Middle Ages to the 20th century, what are the influences and movements that
he

have shaped the changing face of British architecture?

Romano-British culture—and that included architecture along with language, religion,


political organisation and the arts—survived long after the Roman withdrawal. And
although the Anglo-Saxons had a sophisticated building style of their own, little survives to
ac

bear witness to their achievements as the vast majority of Anglo-Saxon buildings were
made of wood.

Even so, the period between the Norman landing at Pevensey in 1066 and the day in 1485
when Richard III lost his horse and his head at Bosworth, ushering in the Tudors and the
Te

Early Modern period, marks a rare flowering of British buildings. And it is all the more
remarkable because the underlying ethos of medieval architecture was "fitness for
purpose". The great cathedrals and parish churches that lifted up their towers to heaven
were not only acts of devotion in stone; they were also fiercely functional buildings. Castles
served their particular purpose and their battlements and turrets were for use rather than

page 15
Telegramdagi kanal: https://t.me/MULTILEVELfreeC1

ornament. The rambling manor houses of the later Middle Ages, however, were primarily
homes, their owners achieving respect and maintaining status by their hospitality and good
lordship rather than the grandeur of their buildings. In a sense, the buildings of the 16th
century were also governed by fitness for purpose—only now, the purpose was very

id
different. In domestic architecture, in particular, buildings were used to display status and
wealth.

This stately and curious workmanship showed itself in various ways. A greater sense of

sh
security led to more outward-looking buildings, as opposed to the medieval arrangement
where the need for defence created houses that faced inward onto a courtyard or series of
courtyards. This allowed for much more in the way of exterior ornament. The rooms
themselves tended to be bigger and lighter—as an expensive commodity, the use of great
expanses of glass was in itself a statement of wealth. There was also a general move

am
towards balanced and symmetrical exteriors with central entrances. With the exception of
Indigo Jones (1573-1652), whose confident handling of classical detail and proportion set
him apart from all other architects of the period, most early 1 7th century buildings tended
to take the innocent exuberance of late Tudor work one step further. But during the 1640s
and 50s the Civil War and its aftermath sent many gentlemen and nobles to the Continent
rJ
either to escape the fighting or, when the war was lost, to follow Charles II into exile. There
they came into contact with French, Dutch and Italian architecture and, with Charles's
restoration in 1 660, there was a flurry of building activity as royalists reclaimed their
property and built themselves houses reflecting the latest European trends. The British
Baroque was a reassertion of authority, an expression of absolutist ideology by men who
he

remembered a world turned upside down during the Civil War. The style is heavy and rich,
sometimes overblown and melodramatic. The politics which underpin it are questionable,
but its products are breathtaking.

The huge glass-and-iron Crystal Palace, designed by Joseph Paxton to house the Great
ac

Exhibition of 1851, shows another strand to 19th century architecture—one which


embraced new industrial processes. But it wasn't long before even this confidence in
progress came to be regarded with suspicion. Mass production resulted in buildings and
furnishings that were too perfect, as the individual craftsman no longer had a major role in
Te

their creation. Railing against the dehumanising effects of industrialisation, reformers like
John Ruskin and William Morris made a concerted effort to return to hand-crafted, pre-
industrial manufacturing techniques. Morris's influence grew from the production of
furniture and textiles, until by the 1880s a generation of principled young architects was
following his call for good, honest construction.

page 16
Telegramdagi kanal: https://t.me/MULTILEVELfreeC1

The most important trends in early 20th century architecture simply passed Britain by.
Whilst Gropius was working on cold, hard expanses of glass, and Le Corbusier was
experimenting with the use of reinforced concrete frames, we had staid establishment
architects like Edwin Lutyens producing Neo-Georgian and Renaissance country houses for

id
an outmoded landed class. In addition there were slightly batty architect-craftsmen, the
heirs of William Morris, still trying to turn the clock back to before the Industrial Revolution
by making chairs and spurning new technology. Only a handful of Modern Movement
buildings of any real merit were produced here during the 1920s and 1930s, and most of

sh
these were the work of foreign architects such as Serge Chermayeff, Berthold Lubetkin and
Erno Gold-finger who had settled in this country.
