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

    A)                 association of 30S, m-RNA with formyl-met-t-RNA

    B)                 association of 50S subunit of ribosome with initiation complex

    C)                 formation of formyl-met-t-RNA

    D)                 binding of 30S subunit of ribosome with m-RNA

    Correct Answer: A

    Solution :

                    During the process of translation an initial complex is formed between m-RNA, 30S ribosomal subunit and methionyl t-RNA. This complex is formed due to association of \[I{{F}_{1}},\,I{{F}_{2}},\,I{{F}_{3}}\] initiation factors and GTP molecule.
