Q. During translation initiation in prokaryotes, a $GTP$ molecule is needed in
AIIMS
AIIMS 2007
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
Solution:
During the process of translation an initial complex is formed between mRNA, $30 S$ ribosomal subunit and methionyl $t$ RNA. This complex is formed due to association of $IF _{1}, IF _{2}, IF _{3}$ initiation factors and GTP molecule.
