C) base sequence differences.
D) hydrogen bonding differences.
E) the ability of each base to pair with any of the other three bases.

Question

Quizplus · Accepted Answer

The diversity in DNA molecules is primarily due to differences in the base sequence. The four different nucleotide bases (adenine, guanine, cytosine, and thymine) can combine in any order to create a vast number of different DNA sequences. This diversity in sequences is what allows for variations in genetic information, which is the basis for differences between individuals, species, and even organisms. Physical shape, size differences, and hydrogen bonding may have structural effects on the DNA molecule, but they do not contribute to the diversity of genetic information. The ability of each base to pair with any of the other bases is also not a primary factor in the diversity of DNA, as the combinations will still be limited to the four nucleotide bases.
