What are the DNA sequences that cap chromosomes and become shorter as cells replicate?
A) telomeres
B) free radicals
C) cellular clocks
D) amino acids

Question

Quizplus · Accepted Answer

Telomeres are sequences of DNA that cap the ends of chromosomes and shorten with each round of cell division. Free radicals are unstable molecules that can damage DNA, but they are not specifically related to chromosome capping. Cellular clocks refer to the internal timing mechanisms of cells, but they do not directly affect telomere length. Amino acids are the building blocks of proteins and are not directly related to telomeres.
