How to slow telomere shortening
WebTelomere shortening results from the inherent inability of complete replication at the ends of the DNA lagging strand (end replication problem). During cell proliferation, DNA is replicated except for a small part that cannot be replicated as described below. The enzyme responsible for replication, DNA polymerase, can only synthesize the new strand in the 5′ … http://www.longlonglife.org/en/transhumanism-longevity/aging/telomere-shortening-causes-consequences-on-aging/
