One of the mysteries of the English language finally explained.
A compound found in living tissue as a constituent base of DNA. It is paired with guanine in double-stranded DNA.
A pyrimidine derivative; chemical formula: C₄H₅N₃O
- ‘The derivatives of purine are called adenine and guanine, and the derivatives of pyrimidine are called thymine, cytosine and uracil.’
- ‘The nitrogen-containing units are the bases: adenine, cytosine, guanine, and uracil.’
- ‘Isochores were defined as long genomic segments that are fairly homogeneous in their guanine and cytosine composition.’
- ‘In DNA the bases pair to form a ladder-like structure, with adenine paired with thymine and guanine with cytosine.’
- ‘During DNA replication, DNA polymerase incorporates unmethylated cytosine opposite to guanine, leading to an overall reduction in methylation of DNA.’
