Question

During translation initiation in prokaryotes, a GTP molecule is needed in

(a) association of 30S, mRNA with formyl met tRNA 

(b) association of 50S subunit of ribosome with initiation complex 

(c) formation of formyl met tRNA 

(d) binding of 30S subunit of ribosome with mRNA

Answer 1

Correct option (a) association of 30S, mRNA with formyl met tRNA 

Explanation

During the process of translation an initial complex is formed between mRNA. 30S ribosomal sub-unit and methionyl tRNA. This complex is formed due to the association of IF₁, IF₂, IF ₃ initiation factors and GTP molecule.
