Structure of HIV

HIV is a spherical enveloped virus of about 90-120 nm diameter .In nucleocapsid is icosahedral. Its genome consists of a single stranded RNA filament segmented into two identical filaments and associated with a reverse transcriptase enzyme. The envelope is comprised of a lipid bilayer derived from host cell membrane, and projecting. Knoblike glycoprotein spikes with pedicles formed virus coded glycoproteins.
