Draw the structure of fructose.
8. Why are there around 41 tRNAs when there are 61 codons coding for amino acids (62 if
including selenocysteine)? Discuss the significance of the wobble position at the 5’ end of
the anticodon on tRNAs.

indicate where antigen binding occurs.
11. How are enzymes classified? Illustrate each class with a general reaction and explain the
types of reactions they catalyze.
