What is the rate of translation in prokaryotes under adequate conditions?

(a) 10 amino acid per second

(b) 20 amino acid per second

(c) 30 amino acid per second

(d) 40 amino acid per second

This question was posed to me during an internship interview.

My query is from Elongation and Termination topic in division Gene Expression : Translation of Cytogenetics

Best answer
Correct option is (b) 20 amino acid per second

Easiest explanation: While the ribosome can read about 50-60 nucleotides per second, due to triplet codon the maximum number of amino acids added per second would be : (60/3) = 20 amino acid per second.
