Answer:

Option A, In DNA, each base pairs up with only one other base.

Explanation:

DNA is made up of two complementary nucleotide (also referred to as base pairs). It is the purine which associates with the pyrimidine group.  

The four bases in DNA are  

• adenine (A) - a purine

• cytosine(C) - a pyrimidine

• guanine (G) - a purine

• thymine (T) - a pyrimidine

Adenine is complementary to thymine and cytosine is complementary to guanine . Thus, Adenine  forms complementary pair with thymine and cytosine forms complementary pair with guanine.

Hence, option A is correct.

fgiga [73]
<span>The correct format for an MLA in-text citation for an article with no known author is A. ("Title" page). The "Title" is the shortened title of the work. It is in lieu of the author's name.
