C) DNA microarray
D) PCR
E) homologous recombination

Question

Quizplus · Accepted Answer

DNA microarray technology allows for the analysis of gene expression for multiple genes at once by examining the amount of mRNA present in a sample. This technology involves the use of a slide or chip with thousands of tiny spots, each containing a different probe that can hybridize with a specific mRNA molecule. The intensity of the fluorescent signal on each spot indicates the amount of mRNA present, giving researchers a snapshot of gene expression levels in the sample.
