Question 1.1. (TCO 2) A microbiologist wants to study the process of viral infection of animal cells. She wants to be able to see the viruses as they enter the cells.

(a) What microscope would you suggest she use for these studies? Why? (5 pts.)
(b) How should she prepare her samples for microscopy? (5 pts.) (Points : 10)

(Microbiology) Due in 10 minutes.

Explanation / Answer

She can use electron microscope to view virus entry in the cell.

Electron microscope has higher resolving power ( higher clarity ) than light microscope because of the use of electrons instead of light. Electron microscope allows the scientist to view structure within a cell. They form an image of the specimen at magnification of 500,000 times. She can also use cryo electron microscopy , electron tomography. --- which shows how virus attaches itself to the cells and assimilate during replication.

She can prepare the slide by using negative staining --- rapid procedure used for viewing small particles such as virus in fluids.
