    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 30 subunit of ribosome with mRNA

    Correct Answer: A

    Solution :

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