Microbiology Human Immunodeficiency Virus (HIV) is a spherical retrovirus surrounded by an envelope composed of a phospholipid bilayer. It is a diploid virus composed of positive single-stranded RNA that codes for 9 viral genes. Two proteins on the surface of the viral envelope are derived from the ''env'' gene, which is essential for viral tropism. Which of the following proteins are required for viral attachment to host T-cell and entry, respectively? A Renal General Principles 2020-10-28T00:14:20Z 2459150.5099537 WBR0341
