Topoisomerase unwinds the coiled DNA. Topoisomerases are enzymes that regulate the winding of DNA molecules. These enzymes are able to cut one of the two paired DNA strands, pass a strand through the cut and religise the cut. This process adds or removes DNA supertours, an important mechanism for genome replication during cell …

Did you know?
WebThe unwinding of the double helix of DNA is caused by an enzyme called helicase, which breaks the hydrogen bonds holding the complementary base pairs together, creating two template strands of DNA ready to begin the next step of replication. The place where this enzyme ‘unzips’ the DNA is called the replication fork.
WebHelicase unwinds the helix, and single-strand binding proteins prevent the helix from re-forming. Topoisomerase prevents the DNA from getting too tightly coiled ahead of the replication fork. DNA primase forms an RNA primer, and DNA polymerase extends the … WebTRANSCRIPTION • The certain portion (gene) of DNA unwinds as the RNA polymerase binds to the promoter site. • The two strands of DNA separate and one strand serve as a template to synthesize the new mRNA strand. • RNA polymerase adds the ribonucleotides containing uracil instead of thymine • The cap is then added in the 5’ end of RNA and po …

DNA polymerase will add the free DNA nucleotides using complementary base pairing (A-T and C-G) to the 3’ end of the primer this will allow the new DNA strand to form. Adenine pairs ...
WebWhat enzyme unwinds DNA during transcription? It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ''read'' the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.
