Date: November 23, 1992 Editor's Note: Indications are that the National Institutes of Health's controversial gene-patenting initiative, now widely seen as moribund, is really as good as dead. At press time, a final decision on the matter was still in the hands of Secretary of Health and Human Services Louis Sullivan, but sources at HHS feel the initiative is on insecure legal footing and will be dropped. Before the proposal more or less gave up its ghost, however, it served to stimulate anim

Photodisc Although President Bill Clinton surely had something in mind during his 2000 State of the Union address when he asked the nation to "celebrate our diversity," insights into human diversity at the molecular level are promising to speed drug discovery and revolutionize medicine to mark- edly improve human health. Individuals differ at one in 1,000 base pairs, which adds up to a whopping number of human genetic variations when applied to the roughly three billion base pairs of the human g
Jumping Genes A Buyers' Guide

Courtesy of Ivan Rayment  CAUGHT IN MID HOP: Structure of the Tn5 transposase/DNA complex No one believed Barbara McClintock in 1951 when she first described DNA that "jumped" from site to site within maize chromosomes, altering the expression of genes near the sites of integration. In due course, these transposable elements, or transposons, were found to be ubiquitous in nature, and 30 years later McClintock won the Nobel Prize. Today transposons have gone from molecular oddity to molec

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
