Breaking apart a strand of dna

WebDNA damage is an alteration in the chemical structure of DNA, such as a break in a strand of DNA, a nucleobase missing from the backbone of DNA, or a chemically changed base such as 8-OHdG. DNA damage can occur naturally or via environmental factors, but is distinctly different from mutation, although both are types of error in DNA.

WebAug 9, 2024 · DNA helicase: DNA helicase is an ATP dependent catalytic enzyme which unwinds the dsDNA for providing leading as well as lagging strand replication. It runs ahead of the replication fork and continuously unwinds the dsDNA, providing the template for DNA polymerase to work. Unless DNA helicase unwinds dsDNA, DNA polymerase can not … Webresponse to DNA double strand break damage [6].
