Question

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

Answer 1

Answer: (A)

association of 30S, mRNA with formyl-met-tRNA

Answer 2

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.
