Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.

Innovations Expand Lab Power, Uses Of PCR Technique
Ricki Lewis | Jul 25, 1993 | 8 min read
The gene amplification technique invented by genetics researcher Kary Mullis on a moonlit drive through the northern California hills a decade ago--the polymerase chain reaction (PCR)-- continues to revolutionize the life sciences. Uses in molecular biology research and in diagnostic tests are proliferating, and PCR is even bringing a new molecular approach to such fields as paleontology and epidemiology. The following companies are among those supplying PCR-related products for the resear
Software Helps Researchers In Sorting Through The Human Genome
Ricki Lewis | Jul 21, 1996 | 10 min read
The Human Genome SIDEBAR : Selected Suppliers of Software for Gene Discovery and Analysis Genetics has been an informational science since the elucidation of DNA's structure. Today's researchers say the field shifted to a more computational mode in 1990-the year that research groups began mapping genes to specific chromosomal sites for the Human Genome Project. "That year was pivotal, because it was then that the need to sequence significant amounts of DNA became compelling," says Richard Gib
Prospecting for Gold in Genome Gulch
Amy Adams | Apr 14, 2002 | 9 min read
The human genome is much like the American West of the 1850s: Everyone wants a piece of the pie. Similar to gold prospectors of 150 years ago, biotech and pharmaceutical companies, and even universities, are frantically searching for the nuggets of gold that will help them find the mother lode—a gene whose function is sufficiently marketable to make all of the preliminary research worthwhile. Companies that do strike gold get to introduce new classes of drugs to the market. Others hope to

Across the animal kingdom, dominance isn’t the only way for a male to score. Colluding, sneaking around, or cross-dressing can work, too.

Erica P. JohnsonApreschool girl with black braids presses a finger to a disk that twists a brightly lit DNA model, transforming its ladder shape into a double helix. Her head bops from side to side in wonder as the towering DNA coils and straightens. When a bigger boy claims her place, the girl joins meandering moms and dads with their charges as they twist knobs, open flaps, and simply stare at flashing helixes and orange information boards: all a part of the museum exhibit called "Genome: The
