how are the ends of linear chromosomes (telomeres) replicated to prevent shortening with each cell division, considering the limitations of template-dependent synthesis

Apr 23, 2019 ... ... DNA replication, each DNA strand is used as a template to make two new identical DNA molecules. In transcription, the coding strand of the DNA ... ... replication enzymes have also been informative (Liu and Lou, 2017; Mueller ... template-directed 5′-3′ polymerase (pol), 3′-5′ exonuclease (exo) and 5 ... If you took the template strand and built a new DNA strand on it (as happens in DNA replication), you would get an exact copy of the original DNA coding strand ... I.
