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]. Double strand break (DSB) repair The mechanisms involved in the repair of DSBs are poorly understood as they are complex and require the accurate coordination of a large variety of proteins that are not only involved in the process of repair but also the recognition of repair, placing the cell ... WebDirectionality, in molecular biology and biochemistry, is the end-to-end chemical orientation of a single strand of nucleic acid.In a single strand of DNA or RNA, the chemical convention of naming carbon atoms in the nucleotide pentose-sugar-ring means that there will be a 5′ end (usually pronounced "five-prime end"), which frequently contains a … the pilot obituaries moore county
