A stands for adenine, one of the four nitrogen-containing bases in DNA. By the rules of complementary base pairing, A always pairs with T (thymine). Adenine is a purine (a base with a double ring structure). T is a pyrimidine (a base with a single ring structure). Each pair of bases always consists of a purine and a pyrimidine. A and T form two hydrogen bonds between them; G and C form three.

What four nitrogenous bases has a pair of DNA double helix?
Deoxyribonucleic acid (DNA) are complementary molecular strands connected by four base pairs. These base pairs are adenine, thymine, guanine, and cytosine.
Is nucleus contains 23 pairs of DNA?
Yes in the cell of human the nucleus contains 23 pairs of chromosomes and each chromosome has one DNA molecule, hence there are 23 pairs of DNA.
Which base in RNA pairs with adeine?
Uracil. There are five bases in RNA/DNA. They are Adenine, Thymine, Guanine, Cytosine and Uracil. In DNA: Adenine pairs with Thymine, and Guanine pairs with Cytosine In RNA: Adenine pairs with Uracil and Guanine pairs with Cytosine
What pairs up with each half of the DNA molecule?
Adenine pairs with Thymine, Cytosine pairs with Guanine
According to the DNA base pairing rules cytosine always bonds with what?
In DNA adenine pairs with thymine. In RNA adenine pairs with uracil.
What are the DNA complementary bases pairs?
In DNA, cytosine (C) pairs with guanine (G) and thymine (T) pairs with adenine (A).
What four nitrogenous bases has a pair of DNA double helix?
Deoxyribonucleic acid (DNA) are complementary molecular strands connected by four base pairs. These base pairs are adenine, thymine, guanine, and cytosine.
What are base pairs in biotechnology?
DNA base pairs.
What are the base pairs that are found in DNA?
The base pairs found in DNA are adenine with thymine, and cytosine with guanine.
Is nucleus contains 23 pairs of DNA?
Yes in the cell of human the nucleus contains 23 pairs of chromosomes and each chromosome has one DNA molecule, hence there are 23 pairs of DNA.
What are the correct base-pairing rules of DNA?
The correct base-pairing rules ofr DNA. . .The base pairing rules for DNA areA pairs with TG pairs with CC pairs with GT pairs with A
Which base in RNA pairs with adeine?
Uracil. There are five bases in RNA/DNA. They are Adenine, Thymine, Guanine, Cytosine and Uracil. In DNA: Adenine pairs with Thymine, and Guanine pairs with Cytosine In RNA: Adenine pairs with Uracil and Guanine pairs with Cytosine
What pairs up with each half of the DNA molecule?
Adenine pairs with Thymine, Cytosine pairs with Guanine
Which are the base pairs in the DNA?
In DNA,adenine----------thyminecytosine----------guanine
According to the DNA base pairing rules cytosine always bonds with what?
In DNA adenine pairs with thymine. In RNA adenine pairs with uracil.
Where is uracil found?
Uracil naturally occurs in RNA. It replaces thymine which is in DNA. So in RNA U pairs with A, and G pairs with C. In DNA T pairs with A, and G pairs with C.
What are the basses of DNA?
Nitrogenous bases of DNA are Thymine, Adenine, Cytosine, and Guanine.Adenine pairs with Thymine and Cytosine pairs with Guanine.
