Along the RNA, draw nucleocapsid protein (p7 protein).
This protein is important for viral RNA translation and packaging.
Also in the capsid, draw integrase and reverse transcriptase proteins – both of which are necessary for the RNA genome of HIV to enter the host DNA.
Next, draw the viral envelope, which is made up of host cellular membrane lipids and proteins; it fuses with the host plasma membrane during infection.
Draw within the inner layer of the viral envelope the viral matrix protein (p17 protein).
Within the matrix, draw the viral protease.
It is necessary for the maturation of the virus: it cleaves a precursor polypeptide to produce key proteins.
Draw envelope spikes traveling from the matrix through the envelope.
The envelope spike is made of three gp41/gp120 heterodimers.
Label the gp41 and gp120 sections of the envelope spike.
