Viruses use the host's machinery to make copies of themselves. however, some human viruses require a type of replication that humans do not normally have. for example, humans normally do not have the ability to convert rna into dna. how can these types of viruses infect humans, when human cells cannot perform a particular role that the virus requires? a) the virus causes mutations in the human cells, resulting in the formation of new enzymes that are capable of performing these roles.b) the viral genome codes for specialized enzymes not in the host.c) the virus infects only those cells and species that can perform all the replication roles necessary.d) viruses can stay in a quiescent state until the host cell evolves this ability.

A35-year-old woman comes to the ed complaining of chest pressure. she has had such episodes intermittently over the last 5 years, usually when sleeping, but over the last year she has had more frequent severe symptoms that are occasionally associated with severe migraine headaches. the pain is midsternal and is described as pressure that extends as a band around her chest. the ed physician is initially dubious that the pain is cardiac in origin, because the woman has no coronary disease risk factors. an ecg, however, shows 2mm st-segment elevation and inverted t waves in leads v1 through v5 and 1mm st-segment depression in leads ii, iii, and avf. before the cardiologist arrives in the ed, the patient's ecg has returned to normal. this repeat normal ecg is obtained after the administration of aspirin, nitroglycerin, morphine, and oxygen. which of the following is most likely for these findings? - diffuse intimal thickening with focal areas of atherosclerotic narrowing - intermittent thrombus formation and lysis in the left anterior descending artery - intermittent thrombus formation and lysis in the right coronary artery - plaque rupture and thrombus formation in the left anterior descending artery - transiently increased coronary vascular tone in the right coronary artery
