Lesson Overview
... The tips of chromosomes are known as telomeres. The ends of DNA molecules, located at the telomeres, are particularly difficult to copy. Over time, DNA may actually be lost from telomeres each time a chromosome is replicated. An enzyme called telomerase compensates for this problem by adding short, ...
