| Direction: Each of these questions contains two statements |
| Assertion [A] and Reason [R]. Each of these questions also has four alternative choices, any one of which is the correct answer. You have to select one of the codes [a], [b], [c] and [d] given below. |
| Assertion [A] The genetic code is degenerate. |
| Reason [R] Most amino acids are coded by more than one codon. |
A) Both A and R are true and R is the correct explanation of A
B) Both A and R are true, but R is not the correct explanation of A
C) A is true, but R is false
D) A is false, but R is true
Correct Answer: A
Solution :
[a] Both A and R are true and R is the correct explanation of A. The genetic code is degenerate. It means that a given amino acid can be coded by more than one codon. For example, serine is an amino acid coded by UCU, UCC, UCA, UCG, AGU and AGC.
