A portion of an mRNA attached to a ribosome reads 5 GACCAUUU

A portion of an mRNA attached to a ribosome reads: 5 GACCAUUUUUGA 3 A tRNA with a histidine amino acid attached is in the P site of the ribosome. Give the three letter code of the amino acid that is attached to the amino group of this histidine. Give the three letter code of the amino acid attached to the tRNA that will enter the A site.

Solution

The three letter code that is ttached to the amino group of the histidine is CAU.

The three letter code of the amino acid attached to the tRNA that will enter the A site is UUU which codes for amino acid Phenyl alanine.
