The sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).

DNA is a double helix composed of two long chains of nucleotides.

In DNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Guanine, Thymine and Cytosine.

During gene transcription, a fragment of DNA called gene is used as template to create an mRNA, which is in turn used as template to create a protein.

The order of nucleotides in a given gene sequence determines the sequence in mRNA and ultimately also the protein sequence that's synthesized from this sequence.

In conclusion, the sisters have different traits because their DNA contains different ORDER OF NUCLEOTIDES (Option A).
