In Comparing Microarrays with Other Methods That Can Be Used

In comparing microarrays with other methods that can be used to study gene expression, when would microarrays be most useful?

A) When you want a detailed investigation of how changes in the environment affect the expression patterns of a single, known gene
B) When you want a detailed investigation of how a single, known gene changes its expression over time
C) When you are interested in knowing how changes in a single, known gene affect the expression of many genes
D) When you are interested in knowing how the expression of a single, known gene changes over evolutionary time
E) When you are interested in whether males express a single, known gene at a higher level than females do
