What is the function of telomerase?
Protects telomeres
Replicates DNA
Synthesizes proteins
Breaks down RNA
Answer
Protects telomeres: Telomerase is an enzyme that adds DNA nucleotides to the ends of chromosomes, known as telomeres. Telomeres shorten with each cell division, and when they become too short, the cell can no longer divide and enters senescence or apoptosis. Telomerase helps maintain telomere length, allowing cells to continue dividing and preventing premature aging and cell death.
