Dna Replication
DNA Replication DNA replication is a biological process that occurs in all living organisms and copies their DNA. The initiation of DNA replication starts with two steps. First an initiator protein unwinds a short stretch of the DNA double helix. Then a protein called helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, pulling apart the two strands. DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule produces two identical copies of the molecule. DNA replication is one of the most basic processes that occur within a cell. Each time a cell divides, the two resulting daughter cells has to contain exactly the same genetic information or DNA as the parent cell. To achieve this each strand of existing DNA acts as a template for replication. DNA replication happens in three steps. The opening of the double helix and separation of the DNA strands, the priming of template strand, and the assembly of the of the new DNA segment. During separation the two strands of the DNA double helix uncoil at a specific location called an orgin. Several enzymes and proteins then work together to prepare the strands for duplication. Last a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. This three-step process generally applies to all cells. DNA polymerase enzymes are essential for DNA replication. They usually function in pairs while copying one double-stranded DNA molecule into two double-stranded DNA, DNA replication. They also play important roles in other processes within cells. DNA replication and DNA polymerase as you can see work hand and hand together. I don’t think one process can work without the
