Viruses

Life cycle of Bacteriophage

Bacteriophage literally means bacteria eater, because they infect bacteria and kill them. It means bacteria are host to the bacteriophage. Like other viruses, bacteriophages are obligate parasites. They are made of genetic material surrounded by protein structure. They need a host for the vital molecular processes like replication, transcription, translation and multiplication. Once, the virus
