Thymine is one of four nucleotide bases found only in DNA; it pairs specifically with adenine through two hydrogen bonds.
The molecule that carries genetic information in all living organisms, where thymine is one of the four bases.
A class of organic molecules which includes thymine and cytosine, these are key components in DNA.
The structure formed by double-stranded molecules of nucleic acids such as DNA. Adenine-thymine pairing contributes to this structure.
