What best describes the potential role of telomeres in the aging process?
A) They are the packets of fuel that feed each cell and that become more porous with age.
B) They are "glue" that binds together the base pairs of DNA molecules and form weaker bonds with age.
C) They are the scrubber cells that clear all debris from our arteries and become less efficient with age.
D) They are a portion of a chromosome that gets shorter until DNA replication is no longer possible.

Telomeres are the protective caps at the end of chromosomes that get shorter every time a cell divides. Eventually, the telomeres become too short, and cell replication can no longer occur. This process is believed to play a key role in the aging process.
