Also I must note that acquired immune deficiency syndrome (AIDS) is closely linked to HIV as it is the developed form of the virus. That is, HIV eventually causes AIDS.
(Bibliography part three)
The human immunodeficiency virus (HIV) is made up of a nucleoid core and the surrounding protein matrix, both surrounded by a lipid envelope. The nucleoid core contains the virus's genetic material (RNA) and the enzyme reverse transcriptase, which are both used by the virus to replicate itself inside the host cell. The proteins gp41 and the gp120 are attached to the envelope; these proteins enable HIV to bind and fuse with a target host cell. Each different strain of the HIV virus has different proteins on its envelope. This is part of the reason why HIV is so hard to fight. I will discuss the fact that there are different strains of
