Question

Quizplus · Accepted Answer

Telomeres lie in a part of the cell DNA at the end of chromosomes and are known to shorten with each cell division until they reach a critical length, leading to cell senescence or death. Therefore, telomeres are thought to be the location where cells lose their ability to replicate. Free radicals are molecules that damage cells and cause aging, but they are not directly related to telomeres. Antioxidants are molecules that help to neutralize free radicals, and atherosclerosis is a disease that occurs when plaque builds up inside arteries.
