One way they do this is to use a DNA microarray to determine the expression levels of genes. When a gene is expressed in a cell, it generates messenger RNA (mRNA). Overexpressed genes generate ...

The field of DNA microarray data analysis is getting increasingly complicated as scientists develop new array technologies and analysis algorithms, yet accurate introductory information on the ...

To compare all the genes of one organism to those of another organism, we must first know how to define the entire gene sequence of each organism. However, looking at all of an organism's genes ...

Microarray Scanners are devices used to measure the fluorescent areas of a DNA microarray to reveal information about the simultaneous activity of thousands of genes. This information can help ...

Expert Rev Mol Diagn. 2013;13(6):601-611. In other situations, normal microarray analysis in the presence of an abnormal karyotype, such as marker chromosomes, is reassuring, as it indicates that ...
