A DNA (deoxyribonucleic acid) chip is a solid support (typically glass or nylon) onto which are fixed single strands of DNA sequences. The sequences are made synthetically and are arranged in a pattern that is referred to as an array. DNA chips are a...

DNA microarrays, also known as "gene chips", refer to nylon membranes or glass slides that contain either synthetic oligonucleotide DNA or cDNA probes. Each probe has unique sequences that correspond to a specific gene. There are thousands of probes on...

The Human Genome Project began in 1990, with the goal of sequencing the complete human genome. The projected time for the project's completion was 40 years. Yet, in 2001, the sequencing was essentially complete. The reason for the project's rapid...

DNA microarrays are tools used to analyze and measure the activity of genes. Researchers can use microarrays and other methods to measure changes in gene expression and thereby learn how cells respond to a disease or to some other challenge. Humans...

A DNA microarray (also commonly known as gene or genome chip, DNA chip, or gene array) is a collection of microscopic DNA spots, commonly representing single genes, arrayed on a solid surface by covalent attachment to a chemical matrix. DNA arrays are...

Homegrown or commercially supplied, the army provides a panoramic view of the genome The late 19805 were heady days for molecular biologists. PCR was only a few years old. The automated DNA sequencer had just been invented. The Human Genome Project was being...

By James Netterwald, PhD The genetic sequencing of many infectious agents has allowed researchers to use DNA microarrays to study disease. Scientists are exploring a number of areas, including host-pathogen interactions and DNA-protein interactions. Faced with the duty of informing the...
