Viruses and viroids differ in structure and the diseases they cause. how
Answers
The infectious agents which have only nucleic acid and no protein coat is called virusoids.ex.potato spindle tubour viriod
The infectious agents which have both nucleic acid and protein coat is called virus.ex.tobacco mosaic virus.
Answer:
Virus- Structure-It is a nucleoprotein made up of protein coat called Capsid. Capsid is made up of capsomers arranged in helical or polyhedral-geometric forms have either DNA or RNA as genetic material which may be single or double stranded.
Usually plant viruses have single stranded RNA; bacteriophages have double or stranded DNA and animal viruses have single or double stranded RNA or double stranded DNA
-Diseases- Small pox, Mumps, AIDS, Influenza(In animals) and mosaic formation,leaf rolling,drawfing(in plants)
Viroids- Structure- Infectious agent, free from DNA and RNA has low molecular weight
-Diseases- Potato spindle tuber disease
