Telomerase is a ribonucleoprotein enzyme that protects and extends repetitive DNA sequences called telomeres at the ends of chromosomes in eukaryotic cells. Its structure includes a catalytic reverse transcriptase subunit (TERT) and an RNA component (TERC) that serves as a template for the enzyme. Using RNA as a template, telomerase adds nucleotides to telomeric DNA, compensating for the shortening that occurs during replication.Primary FunctionThe primary function of telomerase is to preserve t

Telomeres are specialized DNA-protein complexes located at the ends of eukaryotic chromosomes, composed of TTAGGG repeat sequences. Their function is to protect chromosome ends and prevent the loss of genetic information that may occur during DNA replication. Due to the mechanism of action of DNA polymerase, a portion of the DNA is lost from the ends with each cell division, leading to telomere shortening.Telomerase Enzyme and ActivationTelomerase is an RNA-containing reverse transcriptase enzym
