the sisters have distinct characteristics because of the different order of nucleotides in their DNA (Option A).
DNA is made up of two long chains of nucleotides in a double helix. There are four kinds of nucleotides in DNA, each with a different nitrogenous base: cytosine, adenine, guanine, and thymine.
A DNA fragment known as a gene serves as a template for the creation of an mRNA, which in turn serves as a template for the creation of a protein during gene transcription.
The sequence in mRNA and, ultimately, the protein sequence that is produced from this sequence are both determined by the order of the nucleotides in a given gene sequence.
Thus, we can conclude that because of the different order of nucleotides in their DNA, the sisters have distinct characteristics.
