Telomere Biology

Telomeres are protective caps at the ends of our chromosomes, made of repetitive DNA sequences. They prevent chromosomes from fraying or sticking to each other, which is essential for maintaining genetic stability. Each time a cell divides, telomeres shorten. When they become too short, the cell can no longer divide and may become inactive or die, contributing to aging and age-related diseases. Telomere length is influenced by factors like genetics, stress, and lifestyle. Research into telomeres could help us understand aging and develop therapies for age-related conditions.
