The following points highlight the eight important types of microbial mutants. The types are: 1. Auxotrophic Mutants 2. Resistant Mutants 3. Cryptic Mutants 4. Conditionally Expressed Mutants 5. Antigenic Mutants 6. Metabolic Mutants 7. Regulatory Mutants 8. Temperature-Sensitive Mutants. Microbial Mutant: Type # 1. Auxotrophic Mutants: Auxotrophic mutants are those that are nutritionally deficient, i.e., they are unable to synthesize [...]
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 [...]
The following points highlight the top four examples to substantiate the practical implacability of microbial mutants. 1. Induced mutants have been used extensively in the investigation of various biochemical processes, particularly metabolic reactions. Metabolic processes occur via sequences of enzyme-catalyzed reactions and by developing mutants in which the genes coding for enzymes are mutated (altered), the sequence of steps in [...]
