Telomerase is an enzyme that maintains the length of telomeres, which are protective caps at the end of chromosomes that shorten with each cell division. Telomerase plays a crucial role in cell aging and division, and its dysregulation has been linked to various diseases, including cancer and aging-related disorders. Research in the field of telomerase focuses on understanding the molecular mechanisms of its function, its role in disease development, and potential therapeutic strategies targeting telomerase for disease treatment and prevention.
