Within the HIV life cycle, which step occurs just before the virus can undergo biosynthesis and cleavage?Multiple ChoiceNew viral particles are assembled.The virus acquires a new envelope from the host cell's plasma membrane.Reverse transcriptase catalyzes the conversion of viral RNA into DNA.Viral DNA must be integrated into the nucleus of the host cell.

The enzyme inside the HIV matrix that catalyzes the conversion of viral RNA into viral DNA is transcriptase.

How does HIV produce its envelope?Multiple ChoiceThe host cell's plasma membrane provides the components for the viral envelope.The Golgi body within the virus will assemble the envelope.The viral genetic code directs viral machinery to build a viral envelope.The vacuoles within the virus become the new envelope.

Once HIV RNA is reverse transcribed into HIV DNA and integrated into the DNA of a host cells, the viral DNA is called a(n) .

During its replication a DNA virus enters the of the host cell, where several genes are transcribed into messenger RNA.
