On Monday, I was given back my last biology test. Upon looking at one of the questions that I got wrong, I was unable to understand what I did wrong. I attempted to argue my case to my teacher, but she did not think about my arguments before denying them. The question is as follows: One week after babysitting a child with chicken pox, Steve notices that he has a rash and fever. Being a biology student, Steve realizes three things about chicken pox. ... The second has to do with how the chicken pox reproduces itself ... What did Steve come to understand about the points above? (points 1 and 3 were whether chicken pox is a virus and the type of nucleic acid it contains) I answered that the life cycle of the chicken pox virus is the lytic cycle, as Steve is infected with symptoms relatively quickly. My teacher marked this as incorrect, and said that it was the lysogenic cycle in this case as the symptoms came about "One week after..." I tried to tell her that that one week period was an incubation period, as no virus (at least from what I know) shows symptoms as soon as someone is infected. She told me that the lytic cycle is impossible in this case, as cells reproduce too quickly for it to take a week for symptoms to appear. I kindly reminded her that she said cells reproduce (on average) every 12-24 hours, but she seemed to ignore this. I also explained that on an earlier assignment, where we had to research a virus, smallpox (the virus I was assigned) had an incubation period of 2 weeks, but it still followed the lytic cycle. She still didn't take that into consideration. Who is correct, and, if I am, what is another way that I could argue this? P.S. This test question was an attempt at applying our knowledge; we received no prior information about chicken pox specifically - only viruses in general.
