Thymine. 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.

Erwin Chargaff discovered that the amount of adenine in DNA always equaled the amount of thymine. This observation is part of his rules, which state that in double-stranded DNA, the amount of guanine equals that of cytosine as well, highlighting the base pairing relationships crucial for the 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.
