Adenine and Thymine A = T,
Cytosine and Guanine C = G.
Adenine, Thymine, Cytosine, Guanine
A base pairs with T
C base pairs with G
Adenine and Thymine; Cytosine and Guanine.
Adenine (A) always pairs with Thymine (T) and Guanine (G) always pairs with Cytosine (C) because A and G are both purines and C and T are both pyrimidines.
thymine
Guanine pairs with cytosine
Well the base paring rules are the rules that state that cytosine pairs with guanine and adenine those pair with thymine in DNA, and also that adenine pairs with uracil in RNA. On the other hand, the DNA structure is the crosspieces and combinations of four chemicals called nucleotides: adenine, cytosine, thymine, and guanine. Adenine only links with thymine and cytosine only links with guanine. The structure is called a double helix, and is common to all DNA.
Both strands of DNA made of nucleotides come together and start making a helix which makes the bases pair up while the DNA strands are being twisted around like the helix. In the canonical Watson-Crick DNA base pairing, adenine (A) forms a base pair with thymine (T) and guanine (G) forms a base pair with cytosine (C).
It is not a DNA base pair itself, it is a DNA nucleotide base. It does however, form a base pair when bonded with adenine.
In DNA,adenine----------thyminecytosine----------guanine

Uracil. In normal DNA it would be Thymine, but in RNA Uracil becomes the base pair for Adenine.
The base on one strand pair with the base on the other strand, adenine with thymine, and cytosine with guanine, they join together by hydrogen bonds. Parent

Thymine is the complementary base pair for adenine in DNA.
