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 ...

Potential approaches include genome scans in linkage and association studies as well as gene expression profiling methods such as DNA microarrays and proteomics. DNA microarrays can be used for ...

However, this is no longer the case thanks to the widespread use of an innovation known as the DNA microarray, which was first developed in the early 1990s. A DNA microarray (sometimes called a ...

In a microarray experiment the glass slide with the labeled DNA of interest plays a key role. As can be seen, a solid surface (in this example a glass microscope slide) contains thousands of spots.

Urban, and Tim Liedl from LMU Munich has managed to significantly improve such tests using a cutting-edge nanotechnology called DNA origami. In DNA origami, DNA is folded—akin to the Japanese ar ...
