WebDNA ligase is the protein responsible for linking, or ligating, Okazaki fragments together in order to form a single complete DNA strand. This action only necessary on the lagging strand; the leading strand can be made continuously by DNA polymerase since it is able to read away from the replication fork in the 3'-to5' direction.

WebMay 9, 2013 · DNA helicase is the enzyme that is responsible for the unwinding of DNA during/immediately before replication. What type of bonds are broken during the unwinding stage of replication?... WebThe enzyme DNA helicase breaks the hydrogen bonds between the bases in a specific region of the DNA molecule. This causes the two strands to separate and unwind, exposing nucleotide bases. The enzyme RNA polymerase binds to the template strand of DNA at the beginning of the sequence to be copied.
WebThe central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain. However, DNA replication is much more complex than a single enzymatic reaction. What enzyme unwinds DNA in bacteria? An enzyme called helicase unwinds the DNA by breaking the …
