Life cycle of virus
LIFE CYCLE OF VIRUS

  • A VIRUS ATTACHES TO THE SURFACE OF A BACTERIA/CELL

  • THE VIRUS INJECTS ITS GENETIC MATERIAL INTO THE BACTERIA/CELL

  • THE PROTEINS AND GENETIC MATERIAL ASSEMBLE INTO NEW VIRUSES.

  • THE BACTERIA/CELL BURSTS OPEN, RELEASING THE VIRUS. THE VIRUS GOES AND INFECTS OTHER CELLS.
