WebSemiconservative replication describe the mechanism of DNA replication in all known cells. DNA replication occurs on multiple origins of replication along the DNA template strand (antinsense strand). As the DNA double helix is unwound by helicase, replication occurs separately on each template strand (sense strand) in antiparallel directions.This … WebMar 7, 2024 · DNA is replicated according to a defined spatiotemporal program that is linked to both gene regulation and genome stability.

WebSection Summary. DNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After … WebDNA repair mechanisms all depend on the existence of two copies of the genetic information, one in each of the homologous chromosomes. DNA primase makes DNA primers for the synthesis of Okazaki fragments in the DNA lagging strand. The repair of double-stranded breaks by nonhomologous end joining is accurate.
