WebMaintaining stable telomere length is associated with the activation of telomerase. This enzyme is a ribonucleoprotein that compensates for the loss of telomeric DNA by adding repeat sequences to the chromosome ends, using its intrinsic RNA component as a template for DNA synthesis. WebIn egg and sperm cells, an enzyme called telomerase keeps adding more of the repeating sequence onto the end of DNA strands, so that the telomeres in these cells don’t shorten. In other cells, telomerase is less active, leading to the gradual shortening of telomeres over time. This shortening is thought to be one of several factors that ...
