Discovered in the late 1940s, this is known as "The Chargaff's Rules": DNA has equal numbers of adenine and thymine residues (A = T) and an equal number of guanine and cytosine (G = C). This was one of the most important features for Watson and Crick to solve the structure of DNA molecule in 1953.

adenine.
Adenine (A) always pairs with Thymine (T), and Guanine (G) always pairs with Cytosine (C) on DNA molecules. This pairing forms the specific base pairs that make up the double helix structure of DNA.

Chargaff's data showed that for each organism he studied the amount of adenine always equaled the amount of thymine (A=T) likewise, the amount of guanine always equaled the amount of cytosine (G=C).

Erwin Chargaff. "In 1949, Erwin Chargaff, a biochemist working at Columbia University, in New York City, made an interesting observation about DNA. Chargaff's data showed that for each organism he studied, the amount of adenine always equaled the amount of thymine (A=T). Likewise, the amount of guanine always equaled the amount of cytosine (C=G). However, the amount of adenine and thymine and of guanine and cytosine varied between different organisms." -From my biology textbook, "Biology: Principles & Explorations," Holt, Rinehart, and Winston.
adenine.
Chargaff's conclusion was that the amount of adenine in DNA is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine. This is known as Chargaff's rules or base pairing rules.
Adenine (A) always pairs with Thymine (T), and Guanine (G) always pairs with Cytosine (C) on DNA molecules. This pairing forms the specific base pairs that make up the double helix structure of DNA.
Adenine always binds with thymine.
In DNA, adenine always pairs up with thymine. This pairing is based on hydrogen bonding, which allows adenine and thymine to form a complementary base pair.
Thymine always pairs up with adenine in DNA. In RNA, adenine pairs with uracil.
