Hiv genome - Study guides, Class notes & Summaries

Among its many other uses, PCR is finding important applications in early clinical diagnosis of disease. An example is in testing for the presence of viruses to which antibodies do not appear until a long time after infection. Describe how PCR could be used to detect HIV infection at an early stage, including what information about HIV would be needed to begin with. PCR could be used to detected HIV by performing PCR on cells with primers that are designed to amplify the viral HIV DNA that...

A virus has been discovered. The virus has no envelope and consists of a helical capsid surrounding its dsDNA genome. During assembly, the pac site of the genome ensures that it is properly packaged by the capsomeres. Which of the following amino acids is/are expected to be on the capsomere domain that interacts with the pac site? A. lysine B. methionine C. glycine D. arginine E. A and D Answer: A and D Explanation: DNA has a negative charge, so positively charged amino acids, such as...

Drug Discovery • Unlike small molecule drugs (pharmaceuticals), large molecule drugs (biopharmaceuticals) are mainly protein-based o These protein-based drugs are similar to natural biological compounds found in human body or they're fragments that mimic active part of natural compounds Discovery of Pharmaceuticals commences w/ scanning hundreds of compounds, whether w/ actual materials (irrational approach) or virtual simulations (rational approach) • Pharmaceuticals are new che...
