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.
Understanding biology’s software—the rules that enable great plasticity in how cell collectives generate reliable anatomies—is key to advancing tissue engineering and regenerative medicine.
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.
Among the first to discover epigenetic reprogramming during mammalian development, Wolf Reik has been studying the dynamics of the epigenome for 30 years.
Diverse mammals, including humans, have been found to carry distinct genomes in their cells. What does such genetic chimerism mean for health and disease?
