Lentiviruses are a subclass of which virus strain?
-
Retroviruses
-
Adenoviruses
-
Adeno-associated Viruses

- 7.
What cell types can lentiviral vectors infect? (Check all that apply)
-
Non-dividing cells only
-
Actively dividing cells
-
Quiescent cells
Correct Answer(s)
A. Non-dividing cells only
A. Actively dividing cellsExplanation
Lentiviruses can infect non-dividing and actively dividing cells. They are one of the most efficient methods of a gene delivery vector. The only cells lentiviruses cannot gain access to are quiescent cells (in the G0 state) because this blocks the reverse transcription step.Rate this question:

What genes control transgene packaging during lentiviral transduction?
-
Vif, vpr, and vpu
-
Env, nef, and pol
-
Rev, gag, and pol
Correct Answer
A. Rev, gag, and polExplanation
Lentiviral vectors are derived from HIV. 3rd generation lentiviral systems have reduced the number of HIV genes required for transgene delivery to 3, rev, gag, and pol, improving the biosafety of the system.Rate this question:
