E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible.
A study employing CRISPR/Cas9 to explore the evolutionary beginnings of some giant viruses finds evidence their large genomes arose from gene duplications.
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.
