The HIV virus is
spherical
in shape having a diameter of about
100 nm
.
It has a
cylindrical core
,
single stranded linear
RNA,
has an enzyme called
Reverse Transcriptase
surrounded by a
lipid bilayer
membrane interspersed with knobs made up of glycoproteins.
It is
diploid
as it has two copies of RNA.
It is a
retrovirus
capable of making a DNA copy of itself with the help of Reverse Transcriptase enzyme.
The surface looks like a
soccer ball
with glycoproteins on the outer covering.
The protein projects as
12 knobs.
The protein is crucial for the entry of the virus in the host cell.
Lysis of the host cell takes place by which the cell contents flow out and the cell dies
.
