Which of the following statements is true about protein synthesis in prokaryotes?
A) Extensive RNA processing is required before prokaryotic transcripts can be translated.

D) Unlike eukaryotes, prokaryotes require no initiation or elongation factors.

Question

Quizplus · Accepted Answer

In prokaryotes, translation of mRNA can start even before the transcription is completed. This is because the genetic material is not separated within a nucleus as in eukaryotes. Therefore, the ribosomes can bind to the mRNA and begin translation as soon as the start codon is available even if the mRNA is not yet fully transcribed.
