Telomeres are found at the end of chromosomes to protect
genes from reduction during replication
of chromosomes, especially during meiosis
or mitosis. They are composed of repetitive sequences
that do not code for protein. Telomeres become
reducted <span>especially due</span> to the inability of the lagging strand to be completely replicated to the end of the chromosome. However, while
