Question

In a typical application,a DNA microarray is used to compare the ____________________.
A) expression of genes in two different tissues
B) alleles of each chromosome
C) length of DNA fragments in yeast vectors
D) changes in gene sequences within an allele through generations of a single family
E) protein products produced when using different DNA sequencing techniques

Accepted Answer

DNA microarrays are commonly used to compare gene expression in different tissues or between experimental and control groups. They allow scientists to measure the expression levels of thousands of genes simultaneously, making it possible to identify genes that are up- or down-regulated in response to a specific stimulus or condition.
