Telomeres are the caps at the end of each strand of DNA that protect our chromosomes. They have been allegorized commonly as the plastic tips at the end of shoelaces, which are likely to get frayed without them. Similarly, without telomeres DNA strands become damaged. They are actually disposable protective buffers blocking the ends of the chromosomes. They are consumed during cell division but are replenished by an enzyme – the telomerase reverse transcriptaseReverse osmosis is a water purification technology is achieved by which a high percentage of contaminant retention, dissolved and undissolved (up to 99% retention of dissolved salts). When two liquids with different salt concentrations, are separated by a semi-permeable membrane, a pressure difference between either side of the membrane is a function of the concentration difference is established.
