Chromosome Replication, Telomeres, Aging
Lecture no. 27 from the course: Biochemistry and Molecular Biology: How Life Works
Taught by Professor Kevin Ahern | 28 min | Categories: The Great Courses Plus Online Science Course
Examine the cell cycle of eukaryotic cells like our own and the cycle’s effect on DNA replication. Discover that a quirk in the copying of linear DNA leads to shrinking of chromosomes as cells age, a problem reversed in egg and sperm cells by the telomerase enzyme. For this reason, telomerase might appear to be the secret to immortality except its unregulated presence in cells can lead to cancer.
