Question

A tRNA is charged with the amino acid phenylalanine
(a) At what end of tRNA is this amino acid attached?
(b) What is the mRNA codon that coded for phenylalanine?
(c) What is its anticodon?
(d) Name the enzyme responsible for this attachment.

Answer 1

The amino acid is attached to the amino acid acceptor site of the tRNA.

It is one of the 4 sites of the tRNA.

The mRNA that codes for phenylalanine is UUU, UUC.

The anticodon site of the tRNA has a complementary sequence to the mRNA.

The enzyme responsible for this attachment is the amino acetyl transferase.
