In this article we will discuss about:- 1. Discovery of Transformation 2. Process of Transformation 3. Competence 4. Linkage and Gene Mapping. Discovery of Transformation: The phenomenon was first discovered in 1928 from Griffiths experiment with Diplococcus pneumoniae. As this historical experiment has been instrumental for identification of DNA as a hereditary material. Briefly, when a suspension containing a mixture [...]
In this article we will discuss about the meaning and types of transduction of bacteria.
