Telomerase Molecule Bound To Dna
Photograph - Photograph
Artwork of a molecule of the enzyme telomerase (grey) bound to its RNA template and telomeric DNA (coloured). Telomerase is an enzyme that adds DNA sequence repeats to telomeres at the ends of the chromosome. Every time a chromosome is copied, some of its telomere is lost and this must be replaced. Telomerase is a reverse transcriptase that carries its own RNA molecule.
