Question

39. Extraterrestrial life visits Earth. Before meeting with them, they give you a sample of something similar to a virus that all of them naturally have on their bodies. The government needs to determine if this new virus is harmful to life on Earth. Y in the research is to determine what the genetic material of the virus is. You have been told by other researchers that the virus is composed of only two different types of molecules unique to the aliens, which you have decided to call watson and crick. Watson contains element X and crick contains element Z. You grow the virus in two different batches, one of radioactive X and one of radioactive Z. You allow viruses from each batch to infect different cell samples given to you by the aliens, blend the samples in a blender, then centrifuge each. In the batch grown in radioactive X, the liquid was not radioactive, but the solid pellet in the tube was radioactive. In the batch grown in radioactive Z, the liquid was radioactive, but the solid pellet in the tube was not radioactive. What viral molecule was injected into the cells, possibly indicating what the genetic material is made of? our part A. Watson C. Both E. I should have studied more.

Explanation / Answer

The answer to this problem would be

A) watson because radioactive X was seen in the pellet i.e it was injected into the cell.
