Let’s Check
Activity 9 . Now, that you know the essential concepts and terms in the study of
applications and effects of biotechnology and biodiversity to the society. Let’s try to
check your understanding on these concepts. Identify what is being asked in the
following questions below:
Genetic Modification 1. When a scientist is identifying a trait from an organism and
used them to develop an specialized trait of a crop. What is this processed called?
Recombinant DNA Technology 2. In reference to item number 1, what biological
systems/ technology is used by the scientist to modify the trait?
Cartagena Protocol on Biosafety 3. What do you call to the strict compliance to be
implemented prior to the transportation and distribution of living modified organisms?
Geneticaclly Modified Organisms 4. It is a process that aims to address issues with
regard to food security, for agriculture, drug production and even for nutrition.
Genetic Modification 5. It is a process done to plants, animals, or to microorganism
whose genetic makeup has been modified using recombinant DNA methods.
Genetically Conferred Traits 6. Development of vaccines for medicines, injected
hormonal application to poultry industry, treatment for water supplies and etc. are
examples of ______.
2010 International Year Of Biodiversity 7. It has the focus on boosting awareness of
biodiversity’s importance by promoting actions to foster biodiversity.
Genetic Engineering 8. An extraction of DNA from a certain organism with a desired
trait has been inserted to unrelated species.
Genetically Modified Organisms 9. These are also known as transgenic organisms.
Cartagena Protocol On Biosafety 10. A measure that assures safety and mitigates
possible adverse effect to the environment when not followed.
Let’s Analyze
Activity 9. Getting acquainted with the concepts in biotechnology and biodiversity, it
matters that you understand their relevance in the society. Thus, you are required to
explain briefly the following questions:
1. What role does the environment play in addressing the needs of a society?
- The environment is an important issue even when society is faced with
economic crises, wars, and unending social problems. It matters
because Earth is the only home that humans have, and it provides air,
food, and other needs also natural resources.
2. How can people maintain the rich biodiversity in nature?
- We can participate in biodiversity conservation by increasing our
knowledge of environmental issues, increasing our awareness of the
impacts of biodiversity loss, and increasing support for government
policies and actions that conserve our valuable ecosystems. We can
become educators and role models as stewards of the environment by
aiding in the recovery of species at risk and preventing other species
from becoming at risk. Habitat stewardship consists of activities that
range from enhancing the quality of soil, water, air and other natural
resources to monitoring and conserving wildlife species and their
habitat by donating the property to a land trust.
3. In your own words, how is an organism’s genome manipulated?
Traditionally, humans have manipulated genomes indirectly by
controlling breeding and selecting offspring with desired traits. Genetic
engineering involves the direct manipulation of one or more genes.
Most often, a gene from another species is added to an organism's
genome to give it a desired phenotype-.
4. What are the pros and cons of genetically modifying crops?
Pros, GMO practices can be used to produce “designer” crops,
which have more nutrients, grow quicker and produce more yield,
are more resistant to pesticides and use less fertilizer.
Cons, Studies have shown that genetically modified corn and soy fed
to rats led to a higher risk of them developing liver and kidney
problems. These health risks may not be transferable to humans, but
they illustrate the unpredictable nature of GMOs on living things
5. Will you eat GMOs? Why or why not?
- Nowadays, I wouldn’t eat it.
GMO foods have emerged as a promise to solve the challenge of
world hunger, to reduce production costs and the use of
agrochemicals, and to offer superior products that are potentially more
nutritious and more resistant to pests. But, studies have pointed out
lots of problems for humans and the environment that may arise from
the cultivation and consumption of GMO's, such as allergic reactions,
intoxications, tumor formation, biodiversity decline, genetic
contamination and several others.

In a Nutshell
Activity 9. Based from the definition of essential terms and concepts in biodiversity and
biotechnology and from the exercises you’ve done, please feel free to write your
arguments and lessons you’ve learned below.
1. GMOs, or genetically modified organisms are organisms whose genetic material
has been altered using genetic engineering. Genetic engineering is the
modification of an organism's phenotype by altering its genetic make-up. Genetic
engineering is primarily performed by simple mating or gene recombination. A
latter section in this module elaborates further on how genetically modified crops
are created-.
2. Over the last few years, the food we eat has changed drastically. One of the
reasons for this change is because of the introduction of GMOs into the farming
industry. Many people are lead to believe that GMOs are safe but upon further
examination, it’s become very apparent that not only are they unsafe but that the
impacts they have had on our world have been negative. because we might
discover crisis, like pandemic, if we become reckless.
3. DNA present in all our cells acts as a template by which cells are built. The
human genome project, reading the code of the DNA within our cells, completed
in 2003, is undoubtedly one of the great achievements of modern bioscience.
Our ability to achieve this and to further understand and manipulate DNA has
been tightly linked to our understanding of the bacterial and viral world. Outside
of the science, the ability to understand and manipulate this code has far-
reaching implications for society. In this article, we explore some of the basic
techniques that enable us to read, copy and manipulate DNA sequences
alongside a brief consideration of some of the implications for society.
