   In prokaryotes such as E. coli, there are two main DNA polymerases involved in DNA replication: DNA pol III (the major DNA-maker), and DNA pol I, which plays a crucial supporting role we'll examine later.

   Feb 17, 2023 · It happens in the S phase of cell division. DNA must replicate before cells divide so that the two resulting daughter cells contain the same genetic information as the parent cell. DNA replication occurs in the nucleus of all eukaryotic cells and the nucleoid of prokaryotes.

   How does DNA replication occur in a cell?

   • This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied.

   What is a replication helicase?

   • Multiple origin sites exist within the DNA’s structure; when replication of DNA begins, these sites are referred to as replication forks. Within the replication complex is the DNA helicase. This enzyme unwinds the double helix and exposes each of the two strands so that they can be used as a template for replication.

   How does a bacterial replication fork move at 500 nucleotides per second?

   • For a bacterial replication fork moving at 500 nucleotides per second, the parental DNA helix ahead of the fork must rotate at 50 revolutions per second. A DNA topoisomerase can be viewed as a reversible nuclease that adds itself covalently to a DNA backbone phosphate, thereby breaking a phosphodiester bond in a DNA strand.

   Where does DNA replication take place?

   • DNA replication takes place at a Y-shaped structure called a replication fork. A self-correcting DNA polymerase enzyme catalyzes nucleotide polymerization in a 5′-to-3′ direction, copying a DNA template strand with remarkable fidelity.

   What happens when a cell divides?

   • This action is not available. When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.

   What is the purpose of DNA replication?

   • DNA replication’s primary purpose is to enable living organisms to reproduce. The only way to replace the cells is to copy the cell’s information. It is what DNA replication does. After cell division by mitosis or meiosis, the two daughter cells must contain the same genetic information, or DNA, as the parent cell.

    As discussed briefly in Chapter 1, DNA templating is the process in which the nucleotide sequence of a DNA strand (or selected portions of a DNA strand) is copied by complementary base-pairing (A with T, and G with C) into a complementary DNA sequence (Figure 5-2).
