<p>Telomere = Telo&nbsp;[Greek nouns telos (<em>&tau;έ&lambda;&omicron;&sigmaf;</em>) &#39;end&#39; ] + Mere [Greek (<em>&mu;έ&rho;&omicron;&sigmaf;</em>, root: <em>&mu;&epsilon;&rho;-</em>) &#39;part.&#39;], 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&nbsp;when&nbsp;duplication of chromosome is done,&nbsp;the end of the chromosome is shortened.</p>
<p>Telomere consists of repetitive nucleotide sequences. For vertebrates, the sequence of telomere&nbsp;nucleotides is TTAGGG.</p>
 
<p>This TTAGGG sequence is approximately repeated 2,500 times in human telomere.</p>
 
<p>So&nbsp;the shortened part of chromosome means the&nbsp;repetitive part of telomere, by truncation occurred during cell division.</p>
