<p>Telomere = Telo [Greek nouns telos (<em>τέλος</em>) 'end' ] + Mere [Greek (<em>μέρος</em>, root: <em>μερ-</em>) 'part.'], meaning ending part.</p>
<p>Telomere protects the end of the chromosome from degradation by being truncated itself instead of chromosome.</p>
<p>It is known that telomere length is getting shortened during thechromosome replication in cell division,</p> <p>as DNA polymerase cannot continue its duplicating work to the end part of chromosome.</p> <p>So when duplication of chromosome is done, the end of the chromosome is shortened.</p>
<p>Telomere consists of repetitive nucleotide sequences. For vertebrates, the sequence of telomere nucleotides is TTAGGG.</p>
<p>This TTAGGG sequence is approximately repeated 2,500 times in human telomere.</p>
<p>So the shortened part of chromosome means the repetitive part of telomere, by truncation occurred during cell division.</p>
