What base in dna pairs with adenine

adenine can form two hydrogen bonds with thymine. adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA.

Thymine

Explanation:

Nucleic acids (DNA and RNA) are formed by the union of nucleotides, each of which in turn consists of phosphate, pentose and nitrogenous base.

Nitrogenous bases are classified as purine and pyrimidine as follows:

Purine bases: Adenine (A) and Guanine (G) Pyrimidine bases: Cytosine (C), Thymine (T) and Uracilla (U)

In both DNA and RNA, the Guanine nitrogen base (G) binds exclusively to cytosine (C). The difference occurs in relation to the other bases: whereas in DNA adenine (A) binds only to thymine (T), in RNA adenine (A) will always be linked to the nitrogenous base Uracila (U).
