Question

Viruses have the following shapes except: helical, complex, icosahedral, cocci

Viroids are composed of: DNA ONLY, RNA ONLY, Nucleocapsid oNLY, protein ONLY

Viruses are generally considered acellular agents because: are metabolically inert, they do not replicate on their own, they are immotile, all of the above

True or False: a virus contains both DNA and RNA? T/F

Answer 1

1. viruses are not found in cocci shapes, shape is defined by the capsid.

2. Viroids are the smallest infectious agents they are solely composed of a short strand of circular, single-stranded RNA without any protein coat.

3. the viruses are metabolically inert and cannot move or reproduce on their own so all of the above is right answer.

4. False - a virus is known to contain one type of nucleic material either DNA or RNA, which may be single or double stranded.
