CD8 T cells are activated when their T-cell receptor (TCR) recognizes a peptide presented in the context of the cognate MHC-I molecule on an antigen-presenting cell. This interaction is a key element ...

If whole-genome sequencing (WGS) is like clicking through a DVD frame by frame, and if fluorescence in situ hybridization (FISH) is like scanning the scene-selection menu, a new technology may offer ...

Cell biologists and chemists reveal how viral DNA traffics in human cells. They have developed a new method to generate virus particles containing labeled viral DNA genomes. This allowed them to ...

As illustrated with OnScreen Gene Transcription in our May 1 column, OnScreen Science now has a few very nice iPad apps to teach students about DNA and RNA. The OnScreen DNA Model app was the original ...
