Unformatted text preview: conflicts that require the presence of a telomere to solve certain problems. DNA polymerase only allows nucleotides to be added to the 3’ end of a pre-existing polynucleotide, and therefore, the 5’ ends cannot be completed. Consequently, replication causes strands to become shorter and shorter. This continuous shortening would result in the deletion of indispensable genes in the DNA sequence. Telomeres, on the other hand, preserve an organism’s genes from removal during replication. Telomeres, working with other special proteins, inhibit the cell’s systems from detecting and supervising DNA damage....
