Telomerase Activity
Telomerase activity refers to the functional action of the enzyme telomerase, which is responsible for maintaining and extending telomeres—the protective nucleotide sequences located at the ends of chromosomes. In biological research, telomerase activity is studied as a key factor in cellular replication capacity, genomic stability, and aging-related processes.
Telomerase activity varies across cell types and developmental stages and is tightly regulated within biological systems.
