WebApr 10, 2024 · DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own … WebMatch these enzymes involved in DNA replication with their function: 1. Helicase 2. Topoisomerase 3. Primase 4. Polymerase 1. Uses ATP to unwind DNA strands 2. Relieves strain caused by unwinding and prevents supercoiling 3. Synthesizes 10-12 bp RNA sequences that function as primers 4.

WebBefore the lagging strand can begin assembling new DNA nucleotides, which of the following must occur? OH bonds must be broken between the two strands of DNA. RNA primase constructs a short RNA primer. DNA ligase forms a phosphodiester bond between the 3' OH of the growing strand and the 5' phosphate in front of it. WebIn E. Coli, DNA replication begins by the binding of dnaA proteins to 5 sequences within the origin known as dnaA box sequences (HU an IHF also bind). This binding stimulates the cooperative binding of an additional 20 to 40 DnaA proteins to form a large complex The binding of dnaA causes the A/T rich region to denature into separate single ...
