Which of the following used as a antibacterial
Correct Answer: Lysogenic bacteriophage
Description: B. i.e. (Lysogenic bacteriophage) (461, 56, 60-A 84- CP)* The segments of DNA between chromosomal and extra chromosomal DNA molecules within the cells are Transposons (Jumping genes)* Bacteria may possess extranuclear genetic elements consisting of DNA these cytoplasmic carriers of genetic information are termed PLASMOIDS OR EPISOMES, are capable of autonomous replication (Independent replicons) by their ability to transfer genes from one cell to another* Plasmids have become important vectors in genetic engineering**.BACTERIOPHAGES - are viruses that infect bacteria (Lytic agent was a virus and gave it the name bacterio phage)* Important role in the transmission of genetic information between bacteria by the process of transduction**Lysogenic conversion or phage conversion - used as cloning vectors in genetic manipulations. The presence of high concentrations of phage particles upto 108 per ml in some natural waters suggests that they may have role in the control of bacterial population (Antibacterial) in such environments* Bacteriophages are mostly needed for - Bacterial identification*
