   DNA gene-expression microarray
   A process that allows thousands of pieces of DNA that are fixed to a glass slide to be analyzed at one time. It is used to identify the genes (pieces of DNA) in specific cells or tissue that are actively used to make RNA, which then may be used to make proteins.

   DNA microarray
   A DNA microarray (also commonly known as gene chip, 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. Each ...

   DNA Microarray
   A DNA microarray is a high-throughput technology used to measure expression levels of mRNA transcripts or to detect certain changes in the nucleotide sequence. It is an array of series of thousands of microscopic spots of DNA oligonucleotides, called features, each containing picomoles of a specific...
