Bacterial Transformation – Natural and Artificial Methods of DNA Transfer

Bacterial Transformation – Natural and Artificial Methods of DNA Transfer

 Detailed study of transformation as horizontal gene transfer mechanism including competence development, natural transformation (in late stationary phase), artificial methods (chemical/CaCl₂, heat shock 42°C, electroporation), DNA binding and uptake mechanisms, chromosomal vs. plasmid integration, selection of transformants using antibiotic markers, and applications in genetic engineering.

Viroids, Virusoids, and Prions – Unique Infectious Agents Beyond Viruses

Viroids, Virusoids, and Prions – Unique Infectious Agents Beyond Viruses

Comparative study of non-conventional infectious agents: viroids (small circular RNA without protein coat), virusoids (defective RNA requiring plant viruses), and prions (infectious misfolded proteins). Covers structure, mechanism of infection, diseases caused (potato spindle tuber, TSE/mad cow disease), replication without nucleic acid (prions), and diagnostic/preventive measures.
