A strand of messenger RNA is attached to a ribosome and is directing protein synthesis. The next exposed codon of this messenger RNA has the code GAA. It is most likely to bond with a transfer RNA that has which amino acid?

Glutamic acid or Glutamate

Explanation:

This question is describing the process of TRANSLATION, which is the process by which protein is synthesized from a mRNA template. In the process of translation, a molecule called transfer RNA (tRNA) reads mRNA codons and carries its corresponding amino acid to the growing polypeptide chain.

According to this question, strand of messenger RNA is undergoing translation in the ribosome. However, the next exposed codon of this messenger RNA has the code GAA. A tRNA carrying an amino acid that corresponds to the codon GAA will attach to it. This amino acid is GLUTAMIC ACID.

N.B: codon GAA encodes amino acid GLUTAMIC ACID

we would need to see the picture to answer it

what's the question ?
