Verified step by step guidance

Understand that the problem is asking for the amino acid that corresponds to a specific mRNA codon, which is ATA.
Recall that the genetic code is a set of rules used by living cells to translate information encoded within genetic material (DNA or mRNA sequences) into proteins.
The genetic code is read in triplets, called codons, where each codon specifies a particular amino acid.
Consult a codon table, which maps each of the 64 possible mRNA codons to their corresponding amino acids.
Locate the ATA codon in the codon table to determine which amino acid it codes for, which is Isoleucine.
