Summary Introduction
Toexplain: The role of telomerase in cell division.
Introduction: Deoxyribonucleic acid (DNA) is a hereditary material that is found in almost all living organisms. The DNA is a double-stranded helix that contains genetic information for the organism to grow, function, develop, and reproduce.
