Telomerase

What problem does the enzyme telomerase overcome? DNA replication requires an RNA primer to initiate synthesis, which is degraded after priming. The loss of these primers on the lagging strand of the chromosome ends will result in a loss of information with each round of replication. Telomerase is a special enzyme that uses its own RNA template to add telomeric repetitive DNA to chromosome ends.
