Telomere shortening
Lagging strand during DNA replication
Telomeres shorten because of the lagging strand phenomenon that is exhibited during DNA replication in eukaryotes only.

Telomere
The terminal part of a linear chromosome. Replication of the ends of linear DNA molecules requires specialized enzymes or structures. Often the telomers have a DNA sequence with a single-stranded end that can fold into a hairpin structure.

Telomeres
Mammalian cells typically divide only about 50 times.
This limit is set by the presence of repeated sequences of DNA at the tips of the chromosomes called telomeres.

Genomic DNA in fragments of 200-500 kb are linked to sequences which allow them to propagate in yeast as a mini-chromosome (including telomeres, a centromere and an ARS - an autonomous replication sequence).
