The following points highlight the six main types of enzymes that are associated with enzymes and some of them plays a key role in replication. The types are: 1. The Nucleases 2. The Ligases 3. Restriction Enzymes 4. The Polymerases 5. The Swivelases 6. Unwinding Enzymes and Proteins. Type # 1. The Nucleases: Enzymes which catalyse the breakdown of particular [...]
In this article we will discuss about the DNA replication in eukaryotes. In eukaryotes there are only two different types of DNA polymerases in contrast with DNA polymerase I, II and III of prokaryotes. Furthermore the DNA of eukaryotes is a long linear molecule with several replication units. A diploid mammalian cell contains on an average about 6 pg of [...]
In this article we will discuss about the introduction and mechanism of DNA replication. Introduction to DNA Replication: While presenting the double helical model of DNA, Watson and Crick had remarked, "It has not escaped our notice that the specific pairing (of bases) we have postulated suggests a possible copying mechanism for the genetic material." The complementary nature of the [...]
