Question

What aspects of DNA can be used to differentiate species? Select all that apply.

A. Different DNA structures
B. Differences in chromosome number
C. Different DNA base pairs
D. Differences in DNA sequence

Answer 1

DNA sequence and chromosome number can be used to differentiate species. Therefore, the correct option is C, D.

Step-by-step explanation:

The aspects of DNA that can be used to differentiate species are:

1. Differences in DNA sequence: The sequence of nucleotide bases in DNA can vary between species. For example, the amount of adenine, thymine, guanine, and cytosine varies from species to species.
2. Differences in chromosome number: Some species may have a different number of chromosomes than others, which can be used to distinguish between them.

Therefore, options C (Different DNA base pairs) and D (Differences in DNA sequence) are correct.
