In this article we will discuss about the polymers present in the cell wall of bacteria. Apart from murein, several other polymers are present in the cell wall of bacteria. In Gram- positive bacteria, the thick, rigid covering of murein is surrounded by polymers, like teichoic acids and teichuronic acid. Teichoic acids are hydrophilic linear negatively charged molecules and they [...]
The following points highlight the twelve main aspects of mutation and repair of damaged DNA in bacteria. Some of the aspects are: 1. Nature of Bacterial Variations 2. Spontaneous and Induced Mutations 3. Molecular Mechanism of Mutagenesis 4. Physical Mutagenic Agents 5. Mutation Rate and Mutant Frequency 6. Phenotypic Changes Due to Mutation and Others. Aspect # 1. Nature of [...]
