Enhancers, short regions of DNA that direct gene expression, of species separated by 700 million years of evolution worked interchangeably, according to a new study.
Working with a virus that infects bacteria, the Stanford University biochemist and developmental biologist helped to develop a way to stitch DNA together, a discovery that gave rise to genetic engineering.
Wing development in females is environmentally controlled, but in males, an insertion on the sex chromosome appears to dictate whether the insects grow wings, according to a study.
Diverse mammals, including humans, have been found to carry distinct genomes in their cells. What does such genetic chimerism mean for health and disease?
