(a) Name the enzyme responsible for the transcription of tRNA and the amino acid the initiator tRNA gets linked with.
(b) Explain the role of initiator tRNA in initiation of protein synthesis.

Explanation

(a) RNA polymerase in prokaryotes and RNA polymerase III in Eukaryotes is responsible for transcription of tRNA. Initiator tRNA gets linked with methionine in eukaryotes and formulated methionine in prokaryotes.
(b) The initiator tRNA, which is charged with amino acid methionini, reaches the smaller subunit of ribosome. Its anticodon UAC recognises the codon AUG on m RNA and binds by forming complementary base pairs. The large subunit of ribosome joins the smaller subunit and initiates translation.
