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
Bacteria and Humans Have Been Swapping DNA for Millennia
Kelly Robinson and Julie Dunning Hotopp | Oct 1, 2016 | 8 min read
Bacteria inhabit most tissues in the human body, and genes from some of these microbes have made their way to the human genome. Could this genetic transfer contribute to diseases such as cancer?
Jumping Genes A Buyers' Guide
Hillary Sussman | Jun 15, 2003 | 6 min read
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
