Question

Quizplus · Accepted Answer

Oligonucleotides are short, single-stranded DNA sequences that are complementary to a specific gene sequence. Each oligonucleotide on a DNA microarray serves as a unique identifier or probe for a specific gene. The hybridization of labeled cDNA or RNA to the oligonucleotides on the microarray allows the expression levels of thousands of genes to be measured simultaneously.
