Genetic and physical mapping
David Botstein, a prominent Stanford geneticist, talks about his initial involvement in Human Genome Project discussions and the value of genome maps.
Transcript:
I was invited largely because I had been involved in gene mapping, because a few years before in 1980 three colleagues and I had published a proposal for making a genetic map of the human genome with DNA markers that could be useful for finding disease genes. And by the time of the Santa Cruz meeting it was clear not only that you could find disease genes this way, but that it would really be useful to have more infrastructure, mainly a genetic and physical map that would greatly speed up this process.

The critical first step to mapping the genome involved finding genetic markers. These markers are unique sequences that provide orientation points in the genome landscape.
Mary-Claire King talks about the tedious process of hunting for genes in the days before genetic maps (based on thousands of markers) were readily available.
James Watson describes sequencing the human genome using markers and BACs, and Craig Venter explains using cDNA libraries, ESTs, and shotgun sequencing.
Model organisms such as yeast, bacteria, the mouse and the fruit fly are used by researchers to study biological systems. The genomes of these organisms have been mapped and sequenced.
Craig Venter, leader of the private effort at Celera Genomics, speaks about his company's reliance on the public data for reassembly of the Celera sequence.
