In this article we will discuss about the cell division and cell cycle in prokaryotes. Bacterial cell division is also termed as fission. The bacterial chromosome is circular and attached to the plasma membrane at a specific point. Its replication starts from an initiation point. Both the copies of the chromosome are attached to the plasma membrane, close to each [...]
In this article we will discuss about:- 1. Meaning of Plasmids 2. Classes of Plasmid 3. Copies of Plasmids within a Cell 4. Phenotypic Effects of Plasmids 5. Origin of Plasmids and Viruses 6. Uses of Plasmids. Meaning of Plasmids: In bacterial cells, certain autonomously replicating circular genetic elements (DNA) are found some of which can become integrated into [...]
In this article we will discuss about Resistance Plasmid, a Group of Conjugative Plasmids which Confer to their Bacterial Host Resistance to Specific Antibiotics. Meaning of Resistance Plasmid: Resistance factors or resistance plasmids are a group of conjugative plasmids which confer to their bacterial host resistance to specific antibiotics, such as, chloramphenicol, sulphonamide, streptomycin, tetracycline etc., and to several metal [...]
