How is the end replication problem solved
WebFor example, the end replication problem causes a progressive shortening of telomeric DNA at each round of DNA replication, thus telomeres eventually lose their protective capacity. This phenomenon is counteracted by the recruitment and the activation at telomeres of the specialized reverse transcriptase telomerase.Apr 1, 2024 WebFor example, the end replication problem causes a progressive shortening of telomeric DNA at each round of DNA replication, thus telomeres eventually lose their protective capacity.

See Answer Question: What is the end-replication … WebDNA replication is the process by which a cell makes a copy o f its DNA before cell division. In prokaryotes, DNA replication proceeds according to a semi-conservative model, where each new DNA molecule consists of one strand from the original DNA molecule and one newly synthesized strand. The process o f DNA replication can be broken down into ...
