Do you some amino acids have more than one mRNA codon?

Most amino acids are indicated by more than one codon.

Explanation: Because there are only 20 different amino acids but 64 possible codons, most amino acids are indicated by more than one codon so the essential amino acids are coded by more than one codon, so that mutation does not change the amino acid sequence in the peptide chain.

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
