A special type of DNA polymerase enzyme called telomerase catalyzes the synthesis of telomere sequences at the ends of the DNA.
In humans there are 46 chromosomes and thus 92 telomeres (one at each end)
Telomeres also acts as protective caps for chromosomes and separate one chromosome from another in the DNA sequence
Telomeres are also thought to be the "clock" that regulates how many times an individual cell can divide since telomeric sequences shorten each time the DNA replicates.
