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 [...]
In this article we will discuss about the double helix of DNA. On the basis of the evidences available and a knowledge of interatomic distances and bond angles, Watson and Crick proceeded to construct molecular models of DNA. In 1953 they finally postulated a precise, three-dimensional, double helical model which could account for many of the observations on the chemical [...]
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 [...]
