Fundamentals of Microbiology

3.4.1.1 Importance of microbial Genetics

1. Gene function is the basis of cell functions
2. Microorganisms provide simple systems for studying genetic phenomena
3. Microorganisms are used for isolation and duplication of specific genes from other organisms by molecular cloning
4. Microorganisms produce valuable substances such as antibiotics, vitamins, hormones etc., and can be used for large scale industrial processes
5. Genes of higher organisms can be transferred to microorganisms by cloning and can be used for study and industrial processes
6. Disease causing mechanisms can be studied and prevention measures can be arrived at.
