Question

In a microarray analysis used to compare sporulating and nonsporulating yeast, a spot that appears yellow at a given time point is associated with a gene that is _______.
A) is expressed roughly equally in both sporulating and nonsporulating yeast
B) present in sporulating, but not in nonsporulating yeast
C) likely to play a role in the process of sporulation
D) expressed in neither the sporulating nor the nonsporulating yeast

Answer 1

Answer:A) is expressed roughly equally in both sporulating and nonsporulating yeast

Explanation:

Yellow signal is the result of roughly equal parts red and green signals combined. This indicates roughly equal expression levels of the corresponding gene in both yeast samples.
