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 [...]
The following points highlight the three main types of bonds in DNA replication. The types are: 1. Covalent and Ionic Bonds 2. Hydrogen Bonds 3. Weak Chemical Bonds. Type # 1. Covalent and Ionic Bonds: Atoms can attain a more stable arrangement of electrons in their outermost shell by interacting with one another. An ionic bond results from transfer of [...]
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 [...]
