Answer:
The continuation of the question is
Which explains the reasoning behind this fact?
Their DNA comprises different codon sequences.
It is composed of four distinct bases.
Kai received more proteins from one parent compared to the other.
The varied inheritance of amino acids from her parents led to the difference.
The correct response is Their DNA comprises different codon sequences.
DNA, or Deoxyribonucleic acid, consists of nitrogenous base pairs, a phosphate group, and deoxyribose sugar. The amino acids formed from these bases result in varied expression of traits. This variation stems from the diversity in coding sequences since there are over 60 distinct codon combinations. This accounts for the slight differences between Kai and her parents.
