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

  • association of 30S, mRNA with formyl-met-tRNA

  • association of 50S subunit of ribosome with initiation complex

  • formation of formyl-met-tRNA

  • binding of 30S subunit of ribosome with mRNA

Solution

A.

association of 30S, mRNA with formyl-met-tRNA

During the process of translation, an initial complex is formed between mRNA, 30S ribosomal subunit and methionyl tRNA. This complex is formed due to association of IF1, IF2 and IF3 initiation factors and GTP molecule.
