To determine:

The reason behind the ability of scientists to culture HIV

Introduction:

HIV is a human immunodeficiency virus which caused a very serious disease called AIDS (acquired immunodeficiency syndrome). HIV interferes with the immune cells of the body and reduces the ability to fight infections. It kills the T- helper cells and makes the individual vulnerable to infections.

Students have asked these similar questions
Why must primary cell cultures be restarted every so often when preparing primary cell cultures to observe morphological changes caused by cells infected by a virus? Why are tumor cells preferred? Why are non-enveloped viruses generally more resistant to disinfectants than are enveloped viruses? A public health physician isolated large number of phages from rivers used as a source of drinking water in western Africa. They physician is very concerned that humans might become ill from drinking this water, although she knows that the phages specifically attack bacteria. Why is she concerned?
What would happen to a virus that found its way to an environment filled only with cells that were outside of its host range? a) This virus would evolve until it was able to use the surrounding cells as hosts b) This virus would actively transport itself to another area in search of host cells C) This virus would replicate until it found cells that were within its host range d) Nothing; this virus would not be replicated
An antimicrobial drug binds to the HIV reverse transcriptase enzyme, preventing it from working. Which of the following is true of this drug?     It would inhibit early replication steps of some viruses, but not affect normal eukaryotic cell activity.     It would directly interfere with translation of some viral proteins and some eukaryotic proteins.     It would block assembly/maturation steps of some viruses, and interfere with translation in eukaryotic cells.     It would interfere with release of newly formed viruses from a host cell, but not affect eukaryotic cells.     It would interfere with protein synthesis in bacteria, but not affect eukaryotic ribosomes.     It would interfere with mRNA transcription in bacteria and viruses, but not affect eukaryotic transcription.
