telomeraasientsyymillä
Telomeraasientsyymi is the Estonian term for the enzyme telomerase. Telomerase is a ribonucleoprotein reverse transcriptase that adds repetitive DNA sequences to the ends of eukaryotic chromosomes. These repetitive sequences are called telomeres. Telomeres act as protective caps for the chromosomes, preventing them from being damaged or fused with other chromosomes.
During DNA replication, a portion of the chromosome's end, known as the telomere, is lost with each
The activity of telomerase is tightly regulated. In most normal somatic cells, telomerase activity is very
