Question

This protein factor involved in translation is required for translocation of the ribosome and also makes an appearance during termination where it stimulates the release of the uncharged tRNAs.

Group of answer choices

IF-1

EF-Tu GTP

EF-G GTP

RRF

Answer 1

EF - G

EF - G is elongation factor G present in prokaryotes.

It has three main functions -

1. It helps in the exchange of EF Tu GTP with EF Tu GDP during the process of elongation in prokaryotic translation.

2. It helps in the translocation of ribosomes from one codon to the other in prokaryotes during the process of translation.

3. It helps in determination of translation in prokaryotes by binding to released factor which is called as ribosome recycling factor, RRF, in prokaryotes.
