Moreover, DNA replication initiates from a broad initiation … WebThe process is quite rapid and occurs with few errors. DNA replication uses a large number of proteins and enzymes ( Table 11.1 ). One of the key players is the enzyme DNA polymerase, also known as DNA pol. In bacteria, three main types of DNA polymerases are known: DNA pol I, DNA pol II, and DNA pol III.
WebThis 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.
