D) gene expression and the presence of specific rRNA sequences.

Question

Quizplus · Accepted Answer

Microarrays can be designed to detect both the expression of genes and the presence of specific rRNA sequences in a sample. This is accomplished by printing probes on the microarray that are specific to the target genes or rRNA sequences of interest. The sample is then hybridized to the microarray, and the probes that bind to the sample are detected, allowing for the quantification of gene expression and rRNA presence.
