This sample had all the properties of undenatured, double-helical DNA, and behaved in all respects like DNA from non-proliferating sources. The replication cycle of the DNA molecule has thus been shown to consist of an alternation between the four- and two-stranded forms, the latter being the...

Mistakes can happen during every copying process, and the same is true for DNA replication. Do cells have correction systems to fix those mistakes? DNA polymerases from different organisms differ in the fidelity of replication; however, even the best D...
What is copied during DNA replication? DNA Replication in Preparation for Mitosis: The replication of DNA is a critical step during mitosis so that the daughter cells end up with identical copies of the parent cell's DNA. The process involves the enzyme DNA polymerase, along with multiple other...
Despite extensive studies on DNA replication, the exchange mechanisms of DNA polymerase during replication remain unclear. Existing models propose that this exchange is facilitated by protein partners like helicase. Here we present data, employing a comb
This article is a perspective on the separation of the complementary strands of DNA during replication. Given the challenges of DNA strand separation and its vital importance, it is not surprising that cells have developed many strategies for promoting unlinking. We summarize seven different factors ...
During DNA replication, the enzyme ___, catalyzes the elongation of new DNA by adding, to the 3' end of the previous nucleotide, new nucleotides that are complementary to a DNA template. A Helicase. B DNA polymerase. C DNA ligase.
Controls over the timing of DNA replication during the cell cycle of fission yeast The controls acting over the timing of DNA replication (S) during the cell cycle have been investigated in the fission yeast Schizosaccharomyces pombe. The... P Nurse,P Thuriaux - 《Experimental Cell Research》 ...
Topoisomerase IV (TopoIV) is a vital bacterial enzyme which disentangles newly replicated DNA and enables segregation of daughter chromosomes. In bacteria, DNA replication and segregation are concurrent processes. This means that TopoIV must continually
