Question

Of the 64 possible nucleotide codon triplets, how many specify polypeptide chain termination?

Answer 1

Answer:

3.

Explanation:

Translation may be defined as the process of formation of protein product from the RNA molecules with the helps of enzymes and translation factors. Translation occurs in 5' to 3' direction.

There are 64 codons that codes for the twenty amino acids. Three codons are referred as stop codons that result in the chain termination of the translation. Three stop codons are UAA, UAG and UGA.

Thus, the correct answer is option (d).
