(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.

Solution

(a) RNA polymerase III is responsible for transcription of t-RNA and methionine is the amino acid that gets linked with the initiator t-RNA.

(b) Initiator t-RNA carries amino acid methionine at its amino acid binding site and has anticodon UCA at its anticodon binding site. Initiator t-RNA binds with the codon (AUG) present on the mRNA and in this way the initiator t-RNA plays a role in initiation of protein synthesis.
