Telomerase Activity

Meaning

Telomerase Activity is the enzymatic action of the ribonucleoprotein reverse transcriptase enzyme, telomerase, which is responsible for adding repetitive DNA sequences, known as telomeres, to the ends of eukaryotic chromosomes. Telomeres protect the chromosome from degradation and fusion; thus, the activity of telomerase is a critical determinant of cellular lifespan, as it counteracts the progressive shortening of telomeres that occurs with each cell division. Clinically, its regulation is a key focus in longevity and age-related hormonal health research.
