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. WebDNA polymerase only synthesizes DNA in the 5’ to 3’ direction only. The difference between the leading and lagging strands is that the leading strand is formed towards replication fork, while the lagging strand is formed away from replication fork. ...

WebThe same circular DNA molecule can have different numbers of supercoils. These forms are known as topological isomers, or topoisomers. The enzymes that insert or remove supercoils are therefore named topoisomerases. Type I topoisomerases break only one strand of DNA, which changes L in steps WebThe new strand will be complementary to the parental or “old” strand. Each new double strand consists of one parental strand and one new daughter strand. This is known as semiconservative replication. When two DNA copies are formed, they have an identical sequence of nucleotide bases and are divided equally into two daughter cells.
