One of the mysteries of the English language finally explained.
An enzyme that adds nucleotides to telomeres, especially in cancer cells.
- ‘Telomeres, the natural ends of linear chromosomes, are maintained by the specialized reverse transcriptase called telomerase.’
- ‘If any components of the telomerase are missing, telomeres are gradually shortened and most cells die.’
- ‘In eukaryotic cells with telomeres composed of short tandem repeats, this involves the enzyme telomerase.’
- ‘In nature, a chromosome can be lengthened by the enzyme telomerase, which adds new TTAGGG sequences to the end of the telomere.’
