A) light microscopy
B) atomic force microscopy
C) scanning electron microscopy
D) transmission electron microscopy
E) confocal fluorescence microscopy

Question

Quizplus · Accepted Answer

Confocal fluorescence microscopy is used with DNA microarrays to observe gene expression differences. It allows for visualization of fluorescently labeled DNA molecules on the surface of the microarray, allowing for identification of which genes are being expressed at different levels in different samples. None of the other forms of microscopy listed are suitable for observing gene expression using DNA microarrays.
