A DNA chip OR DNA microarray can be used to A. mutate genes of interest B. isolate genes from eukaryotic cell nuclei C. assay protein output from a genomic database D. trap genes that are both active and inactive E. scan a population of nucleic acids for abundance and mutations

isolate genes from eukaryotic cell nuclei C.

Explanation:

A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome

In an mRNA or gene expression profiling experiment the expression levels of thousands of genes are simultaneously monitored to study the effects of certain treatments, diseases, and developmental stages on gene expression. For example, microarray-based gene expression profiling can be used to identify genes whose expression is changed in response to pathogens or other organisms by comparing gene expression in infected to that in uninfected cells or tissues.
