In each type of cell, like a muscle cell or a skin cell, different genes are expressed (turned on) or silenced (turned off). If the cells that are turned on mutate, they could—depending on what role ...

As difficult as it was to sequence the 3.1 billion chemical “letters” that make up human DNA, the harder task may be to figure out what they mean. Trying to determine what’s going on in a particular ...

Students model how scientists use DNA microarrays to determine levels of gene expression in breast cancer patients, and then choose treatments based on what they learn. Normal-functioning DNA codes ...

Two of the critical issues that arise when examining DNA microarray data are (1) determination of which genes best discriminate among the different types of tissue, and (2) characterization of ...

Microarray technology has come of age as a powerful approach to revealing the genome and its dynamic expression through the application of gene-hybridization or gene-expression microarrays. While the ...

A standard Internet protocol that checks errors made during email transmissions has now inspired a revolutionary method to transform DNA microarray analysis, a common technology used to understand ...

In a recent study posted to the Research Square* preprint server, researchers differentiated between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants using nanotechnology. Study: ...

BUFFALO, N.Y. -- A multidisciplinary team of pharmaceutics and computer-science researchers at the University at Buffalo, one of very few teams in the nation applying DNA microarray technology in ...

The late 1980s 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 debated in Congress.

CAMBRIDGE, Mass.--Just as the printing press revolutionized the creation of reading matter, a "nano-printing" technique developed at MIT could enable the mass production of nano-devices currently ...
