    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

    Correct Answer: A

    Solution :

                     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 \[I{{F}_{1}},\text{ }I{{F}_{2}},\text{ }I{{F}_{3}}\]initiation factors and GTP molecule.
