Question

Quizplus · Accepted Answer

DNA chips, also known as microarrays, are used to determine which genes are silent or being expressed. They do this by allowing researchers to compare the expression levels of thousands of genes at once, and to identify which genes are upregulated or downregulated under different conditions. While DNA chips can be used in other applications such as sequencing and fingerprinting, determining gene expression is their primary use.
