Which of the following features is NOT true for a retrovirus?

The membrane of a retrovirus contains glycoproteins, which are capable of binding to a receptor protein on a host cell.

Inside the cell there are two strands of DNA that have three enzymes, protease, reverse transcriptase and integrase.

Inside the cells, reverse transcriptase makes a complementary strand of DNA from the retrovirus RNA and the RNA is degraded.

Inside the nucleus, the DNA is incorporated into the host cell DNA with the aid of integrase.

Ribosomal units are employed to transcribe the viral mRNA into amino acid sequences that can be transformed into proteins in the RER.
