Watch two leading virus reasearchers explain how they use both simple and sophisticated technologies to detect and fight infectious agents.
Animation
The public Human Genome Project started by identifying unique marker sequences distributed throughout the genome. Then, many copies of a small section of DNA were randomly cleaved into smaller fragments, and each small fragment was sequenced. Because there were originally many copies of the DNA in...
Animation
In shotgun sequencing many copies of the entire genome are "blown up" into millions of small fragments. Each small fragment is sequenced. Powerful computers then assemble the individual fragments into the original configuration. Repeat sequences pose a problem for this approach because their sizes...
Animation
A sample is put on a Virochip microarray, and results are compared to databases of all known viral sequences.
Animation
A useful technique for narrowing down the location of a gene involves comparing the chromosomes of affected siblings. Two sisters with Rett syndrome allow researchers an opportunity to map the most likely location of the gene by excluding areas of the chromosome that are not alike.
Animation
Gene chips, also called DNA microarrays, have a broad range of applications in current research, including enabling researchers to measure the activity of thousands of genes simultaneously. Dr. Eric Lander describes the process used to manufacture gene chips.
Video Clips
Peter Skewes-Cox, and Dr. Graham Ruby, both in the DeRisi lab, explain state-of-the-art DNA sequencing and bioinformatic technologies.
