DNA Base pair

DNA base pair

Two complementary DNA bases joined across opposite strands: adenine pairs with thymine, and cytosine with guanine.

Overview

EXPLORE BY LEVEL

The bases on DNA's two strands pair in a dependable way: A with T and C with G. These matching pairs hold the strands together and help a cell copy the sequence.
