In this article we will discuss about the chemical and physical types of mutagens. 1. Chemical Mutagens: Singer and Kusmierek (1982) have published an excellent review on chemical mutagenesis. Some of the chemical mutagens and mutagenesis are given in Table 9.3, and described below: i. Base Analogues: A base analogue is a chemical compound similar to one of the four [...]
In this article we will discuss about:- 1. Meaning of Mutations 2. Occurrence of Mutations 3. Expression. Meaning of Mutations: Inheritance is based on genes that are faithfully transmitted from generation to generation in microorganisms (in all organisms). Despite the biochemical mechanisms that facilitate such transmissions faithfully, sudden change in the sequence of nucleotide bases in genes can and do [...]
