Which part of an animal virus is not reproduced in multiple copies?

  • Capsid

  • Protein

  • Envelope

  • Ribosome

D.

Ribosome

Virus is a nucleoprotein particle. It is made up of an outermost covering known as envelope, a protein coat, ie, capsid and a core of nucleic acid. During its reproduction, multiple cpoies of envelope capsid and nucleic acids are formed inside the host cells.

Since, ribosomes are absent in virus cells. Therefore, they are not reproduced during reproduction of viruses.
