Answer 1

33) False

Virus cannot synthesized protein as they lack ribosome and must use the ribosome of their host cell to translate viral messenger RNA into viral proteins.

34) D

Reterovirus can cause cancer in a variety of species including humans. They appear to cause cancer via mutation of the expression of the expression of the potentially oncogenic host genes.

35) true

The nucleic acid and protein of each class of viruses assemble themselves into a structure called a nucleoprotein or nucleocapsid. The protein and nucleic acid consituents have peoperty unique for each class of virus , when assemble, they determine the shape and size of the virus of that specific class.

36) D

Poxviridae are a diverse group of large complex double stranded DNA virus that replicate in the cytoplasm of the host cell. ( group 1 virus)
