As you well know, coronavirus has been causing major problems on a global scale. Like HIV, coronavirus can replicate within living host cells and can lead to death in some individuals. Which of the following represents a difference between HIV and coronavirus?

Consider the data below. Cells were infected with virus A in one tube or virus B in a second tube at the 0 time point. At 5-minute intervals, a sample of the virus and cell mixture was removed from the tube. The intact cells were removed from the sample, and the number of viruses per milliliter of culture was determined.Using the data in the figure below, approximately how long does it take for virus A to go through one lytic cycle?

Students who take this exam are expected to NOT engage in any form of academic dishonesty. This includes using information from any outside resources such as textbook, internet, and others. You are, however, allowed a “cheat sheet”- one side of one-half of a standard 8.5 x 11 piece of paper with HAND-WRITTEN notes. Hold your “cheat sheet” up to your webcam so that it is visible for about three seconds (failure to do so may result in a score of 0 for this exam).  Indicate your willingness to NOT engage in academic dishonesty by indicating your response below. Note: you must choose option “a” in order to receive credit for this exam.
