Thymine
Definition
Thymine (T) is one of the four nucleotide bases in DNA, with the other three being adenine (A), cytosine (C) and guanine (G). Within a double-stranded DNA molecule, thymine bases on one strand pair with adenine bases on the opposite strand. The sequence of the four nucleotide bases encodes DNA’s information.
Narration
