Botany - Biological Classification Question with Solution | TestHub

Virus is an infectious agent having a genetic material (DNA or RNA) enclosed by an organic material that can replicate inside a host organism. Viruses are known to infect all forms of living organisms. These are obligate parasites. The genetic material is enclosed by a protein capsid and not a cell membrane. Since these lack metabolic pathways and cell wall is absent, antibiotics are ineffective against virus.
