Derived from the greek word telos, which means end and meros, which means part, the word telomere was created.
"Telomeres are an essential part of human cells that affect how our cells age.
Telomeres are the caps at the end of each strand of DNA that protect our chromosomes, like the plastic tips at the end of shoelaces. With out the coating, shoelaces become frayed until they can no longer do their job, just as without telomeres. DNA strands become damaged and our cells can't do their job". -tasciences.com
