They also knew that there was a string of DNA at the end of each chromosome called a telomere, which shortened a tiny bit each time a cell divided, like time ticking off a clock.

The result was a type of cell known as a tetraploid cell, which contains four complete sets of chromosomes rather than the usual two.
