As 2003 marks the completion of the human genome sequence and the 50th anniversary of the discovery of the DNA double helix, the Internet has exploded with noteworthy Web sites on the topic. The following represent just some of what the Web has to offer. The first site is the homepage of the National Human Genome Research Institute (1) -- a good place to start even if the content and presentation are somewhat less engaging than they could be. The next Web site (2) comes from the UK's Wellcome Trust, offering a comprehensive introduction to the human genome -- "the science, its role in health and medicine, and the broader social impact of unraveling its mysteries." The next two sites -- both from PBS's NOVA contain dozens of essays, interviews, multimedia tutorials, video clips, and other engaging features on DNA and genomic research. The first of the two is the companion Web site for "Cracking the Code of Life," a documentary originally broadcast April, 2001 (3). The second, the companion site for "The Secret of Photo 51," presents an intriguing look at Rosalind Franklin, the molecular biologist whose work played an integral role in the discovery of the DNA molecule, but who received no credit for her contribution (4). _Nature_, the journal that published Watson and Crick's original paper on the discovery of the DNA double helix in 1953, offers a Web focus "containing news, features and web specials celebrating the historical, scientific and cultural impacts of the discovery of the double helix" (5). National Public Radio's Science Friday recently broadcast an interview with Watson, who talks about his life in genetics. Audio of entire broadcast is available in this Web site (6). For an in-depth consideration of the significance and ramifications of genomic research, readers may wish to browse through _The Genomic Revolution: Unveiling the Unity of Life_, an electronic book from the National Academies Press (7). And on the lighter side, MSN's online publication _Slate_ offers a collection of 20 editorial cartoons featuring the human genome (8).
