Virology

human immunodeficiency computer computer virus-VIROLOGY human immunodeficiency virus-1, Human immunodeficiency computer virus, is a lentivirus (1). The lentivirus is a member of the retrovirus family (1).The reproductive cycles/second of human immunodeficiency virus-1 has a series of move that include enlargement, entry, uncoating, gene scene, genome replication, concourse and egress/budding (2). viral carrel tropism is the type of carrels a particular virus infects (2). human immunodeficiency virus-1 hindquarterss versatile immune cells with its main target being the lymphocyte CD4 partner cell, part of the T cell group (2). Attachment of the human immunodeficiency virus virus happens once the virus comes into contact with a T cell(2). Env, an HIV protein, codes for gp160-glycoprotein (3). Gp160 is a precursor to gp120 (cap) and gp41(stem)(3). Gp120 and gp41 aid the HIV virus in attaching to the T-cell co-receptors (4). Gp41 attaches to CD4 receptors and gp120 attach es to CCR5 or CXCR4 receptors, cognise as beta-chemokine receptors (2). Entry of the virus into the cell is mediated by gp120 (2). Upon completion of attachment to CD4 , gp120 releases proteins that cashier apart allowing the hidden gp41 to attach the beta-chemokine receptors (2). The viral envelope of the HIV virus comes into contact with the entertain cell membrane; where spinal fusion occurs and the nucleocapsid of the viral protein is inserted into the military cell(2). Uncoating of the HIV virus is the actual unraveling of the nucleocapsid, where the ribonucleic acid genetic core of the virus is located (2). Gene expression is achieved by call on transcription(RT) (2). snarf transcription is when a single abandon RNA is reborn to double stranded desoxyribonucleic acid (2). This is done by reverse transcriptase which HIV uses to manipulate the T-cell cycle to reproduce the HIV virus (2). The horde cell cytoplasm contains nucleotides that make this deal possible (2 ). When viral DNA is then inserted into the ! host DNA integration has occurred (4). expatriate of the viral DNA is carried out by viral protein R (VPR) (2). It transports the viral DNA across the cell membrane to the host cell nucleus,...If you want to get a full essay, point it on our website: BestEssayCheap.com
