C) DNA microarray
D) PCR
E) Homologous recombination

Question

Quizplus · Accepted Answer

DNA microarray technology allows researchers to simultaneously monitor the expression of thousands of genes. It involves attaching short DNA sequences (probes) that are complementary to specific genes onto a surface known as a microarray chip. The labeled RNA sample is hybridized to the microarray chip, and the resulting pattern of labeled spots represents the level of expression for each gene in the sample.
