69) in the first round of translation in Sheeppoxviruses the products are a. the proteins go back to the nucleus b. are composed of structural and non-structural proteins. c. this round of translation happened before the DNA genome replication d. among these products are the cellular RNA polymerase.

If the HIV did not have a reverse transcriptase enzyme, then which of the following would apply? Select one: a. The virus can make use of the reverse transcriptase enzyme from the host cell to convert its RNA into DNA b. Viral particles will be produced without reverse transcriptase enzyme since the original HIV is an RNA virus and needs to assemble RNA ant coat proteins together c. The virus will manufacture its proteins from its RNA using translation and ribosomes from host cell d. Provirus will not be formed and assembly of viral particles will never occur e. The virus will not be able to recognise the host cell and therefore entry into the cell is blocked
