Question

Quizplus · Accepted Answer

DNA microarrays are commonly used to compare gene expression in different tissues or between experimental and control groups. They allow scientists to measure the expression levels of thousands of genes simultaneously, making it possible to identify genes that are up- or down-regulated in response to a specific stimulus or condition.
