Adenine most closely resembles Guanine.
In nucleic acids, the base that pairs with guanine is cytosine.
cytosine
Adenine and Guanine are the two purines used as nitrogen bases in nucleotides. They form complementary base pairs with thymine and cytosine in DNA and with uracil and cytosine in RNA.
Thymine and cytosine are two nitrogen bases found in DNA. DNA is composed of thousands of nucleotides which are composed of one of four nitrogen bases. Both of these nitrogen bases are also pyrimidines, or they have one ring like structure See related link for more info on thymine, cytosine and pyrimidines.
In DNA, the nitrogen base adenine (A) pairs with the nitrogen base thymine (T), and the nitrogen base cytosine (C) pairs with the nitrogen base guanine (G). So the base pairs are A:T and C:G. One way to remember is that A:T spells the word "at."
Thymine most closely resembles cytosine because they both have a single-ring structure (pyrimidine) and are hydrogen bond complementary bases in DNA.
In nucleic acids, the base that pairs with guanine is cytosine.

The nitrogen bases for DNA are adenine, guanine, cytosine, and thymine
Cytosine, a pyrimidine (sugar) base, pairs with Guanine, a purine (nitrogen) base.
pyrimidines
Guanine bonds with cytosine through three hydrogen bonds, forming a stable base pair in the DNA double helix.
The nitrogen base that is sometimes referred to as C is cytosine. It is a compound found in living tissue as a constituent base of nucleic acids.
