Question

Assertion: One codon may code for more than one amino acid.

Reason: A codon is degenerate and ambiguous.

(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 correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option(d) A and R are false

Explanation:

The relationship between the sequence of amino acids in a polypeptide and nucleotide sequence of DNA or mRNA is called genetic code. The genetic code is a triplet. One codon codes for only one amino acid, hence it is unambiguous anil specific. Some amino acids are coded by more than one codon, hence the code is degenerate.
