Web2 de abr. de 2024 · Abstract. The fidelity of DNA replication is a critical factor in the rate at which cells incur mutations. Due to the antiparallel orientation of the two chromosomal DNA strands, one strand (leading strand) is replicated in a mostly processive manner, while the other (lagging strand) is synthesized in short sections called Okazaki fragments. WebFidelity of replication means replication of DNA and the production of accurate daughter DNA using the parental DNA as a template. Cell reproduction depends on the precision …
