DNA - Wikipedia A distinct group of DNA-binding proteins is the DNA-binding proteins that specifically bind single-stranded DNA. In humans, replication protein A is the best-understood member of this family and is used in processes where the double helix is separated, including DNA replication, recombination, and DNA repair. DNA and RNA Probe Labeling | Radiolabeled Nucleotides Labeled nucleotides may be incorporated by a variety of methods including in vitro transcription with SP6, T3 or T7 RNA polymerase, 3' end labeling with ... What is DNA replication? - YourGenome The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new. Following replication the new DNA automatically winds up into a double helix. DNA ligase - Wikipedia DNA ligase is a specific type of enzyme, a ligase, (EC 6.5.1.1) that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.It plays a role in repairing single-strand breaks in duplex DNA in living organisms, but some forms (such as DNA ligase IV) may specifically repair double-strand breaks (i.e. a break in both complementary strands of DNA).
