  • How Does Telomerase Work?

    Telomerase is a crucial enzyme that controls and maintains telomeres. These are the tips of chromosomes that a) protect DNA from molecular attack and b) prevent strands of genetic material from sticking to each other. The enzyme is active in stem cells, germ cells, and tumour cells.
