Question

Quizplus · Accepted Answer

Stem cells in the intestinal walls divide frequently in order to constantly regenerate the lining of the intestines. Division of cells leads to the shortening of telomeres, the protective ends of chromosomes. Therefore, in order to maintain the long-term viability of these cells, they are likely to have high levels of telomerase, which is an enzyme that adds telomeric DNA to the ends of chromosomes to counteract telomere shortening.
