The procapsid is assembled with the aid of ...................... proteins.

  • A.Ladder
  • B.Framing
  • C.Scaffolding
  • D.Form

Answer: C

The procapsid is assembled with the aid of Scaffolding proteins.

In many viruses, including tailed bacteriophages such as P22 and T4 and the herpesviruses, scaffolding proteins guide the coat proteins into a correctly shaped empty shell, the procapsid. They are then released or broken down as the DNA is packaged and the shell matures into the capsid.

'Ladder', 'framing' and 'form' proteins are not terms used for this role.
