Microarrays
A microarray is a tool that allows researchers to analyze the expression of hundredstothousands of genes at the same time on a single glass slide. After attaching segments of singlestranded DNA to a slide in a grid pattern, different DNA samples can be hybridized to the microarray and the resulting fluorescence patterns reveal the genetic makeup of the samples.
Explore this interactive to discover how microarrays can be used to study cancer genes, determine chromosomal abnormalities in patients, or screen foods for pathogenic bacteria.
Choose the appropriate microarray, then select which samples to analyze for hybridization.
