Answer:

Yes

Explanation:

There are two strands of a DNA that are twisted into a helix. Those two strands are formed by pairs of nitrogenous bases that are connected to each other. On the side of the nitrogenous bases are the five carbon sugar and a phosphate. The two sides of the helix are held together by weak bonds, that's why it is easy to create DNA replications from a parent cell to the offspring.

The nitrogenous bases are paired specifically in the DNA:
Adenine (A) pairs with Thymine (T) (vice-versa)
Cytosine (C) pairs with Guanine (G) (vice-verse)
