Question

What is an advatange of the degenerate genetic code?

a. Mutations are more likely to alter proteins, increasing the rate of evolution.

Mutations are less likely to alter protein sequence, decreasing the chances that a mutation will have deleterious consequences to the organism.

c. It increases the number of different proteins that can be coded by each gene.

d. It decreases the total number of tRNAs that have to be made.

a. Mutations are more likely to alter proteins, increasing the rate of evolution.

c. It increases the number of different proteins that can be coded by each gene.

d. It decreases the total number of tRNAs that have to be made.

Explanation / Answer

Option B is the right answer.

The genetic code is degenerate means that one amino acid is coded by many codons. This is advantageous in many ways like it allows tRNA to proofread mRNA, lessens chances of deletion mutation, helps in conservation of genetic material etc.
