Molecular Basis of Inheritance Question 75
75. During translation initiation in prokaryotes, a GTP molecule is needed in
[2003]
(a) association of $50 S$ subunit of ribosome with initiation complex
(b) formation of formyl-met-tRNA
(c) binding of $30 S$ subunit of ribosome with mRNA
(d) association of $30 S-mRNA$ with formylmet-tRNA
Show Answer
Answer : a
Hints & Solution
(a) For the formation of initiation complex during translation of $m RNA, GTP$ is also required. The initiator AUG codes for the formylmethionine in prokaryotes.
