Definition of thymine in English: thyminenoun ˈθʌɪmiːn mass nounBiochemistry A compound which is one of the four constituent bases of nucleic acids. A pyrimidine derivative, it is paired with adenine in double-stranded DNA. Alternative name; 5-methyluracil; chemical formula: C₅H₆N₂O₂ Example sentencesExamples - The film's name comes from the initials of the four DNA bases of our genetic code: guanine, adenine, cytosine and thymine.
- Of the four bases that make up DNA - adenine, thymine, cytosine and guanine - only cytosine has the potential to be methylated in humans and most mammals.
- In DNA the bases pair to form a ladder-like structure, with adenine paired with thymine and guanine with cytosine.
- The derivatives of purine are called adenine and guanine, and the derivatives of pyrimidine are called thymine, cytosine and uracil.
- The nitrogen-containing bases are adenine, thymine, cytosine, and guanine; these names are used to identify the nucleotides.
