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 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...
Genetic evidence shows that humans evolved in Africa and continue to evolve.
New technologies like the Virochip harness DNA's properties to identify and fight new viruses.
In four presentations, Stuart L. Schreiber, PhD, and Eric S. Lander, PhD, open a window onto the fast-paced world of genomic science and chemical genetics.
Dr. Eric Lander takes us on a tour of this remarkable genetic century, describing the rapid advances in DNA sequencing technologies and information science.
Dr. Lander explores human genetic variation and how it may affect individual susceptibility to certain diseases.
