The linear chromosomes ends in eukaryotes are protected by telomeres, a nucleoprotein structure that contains telomeric DNA with repetitive sequence and associated proteins. Telomerase is an RNA-dependent DNA polymerase that adds telomeric DNA repeats to the 3'-ends of chromosomes to offset the loss of terminal DNA repeats during DNA replication. It consists of two core components: a telomerase reverse transcriptase (TERT) and a telomerase RNA (TR). Telomerase uses a short sequence in its integral RNA component as template to add multiple DNA repeats in a processive manner.
