Protein Synthesis

Q1: Protein synthesis rates in prokaryotes are limited by the rate of mRNA synthesis. If RNA synthesis occurs at the rate of 50 nucleotides/sec, then rate of protein synthesis occurs at

A 10 amino acids/sec

B 17 amino acids/sec

C 25 amino acids/sec

D 50 amino acids/sec

ANS:B - 17 amino acids/sec

It has been found that the rate of transcription and translation are nearly similar.

Rate of transcription = 50nt/sec.
As the rate of transcription = rate of translation.

So, 50nt will code for 16.6 amino acids in a sec which is near to 17 amino acids/sec.
