Explanation:

To encode a single amino acid, a triplet code (codon) is required. This codon is a combination of three nucleotides of either Adenine, uracil, guanine or cytosine and are usually present in the DNA sequence.

A good example is GGA, a codon made up of three units of guanine + guanine + Adenine, and code for the amino acid Glycine

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
