Base pair

In molecular biology, two nucleotides on opposite complementary DNA strands that are connected by hydrogen bonds are called a base pair (often abbreviated bp). 

In DNA pairing, adenine (A) forms a base pair with thymine (T),
to form an A/T base pair.
Guanine (G) pairs with cytosine (C) in DNA, to form a G/C base pair.
