Which statement best describes the major advantage of using microarrays rather than RT-PCR to detect gene expression differences across the genome?
A) Microarrays can test one gene at a time.
B) Microarrays do not require reverse transcription in order to detect gene expression.
C) Microarrays do not require the production of synthetic oligonucleotides.
D) Microarrays can be utilized to study nonexpressed genes.
E) Microarrays can quickly detect the expression of many genes.

Question

Quizplus · Accepted Answer

Microarrays can detect the expression levels of thousands of genes simultaneously, while RT-PCR only tests a small number of genes at a time. Therefore, microarrays offer a more efficient way to study gene expression differences across the genome.
