Scientists use light to 'tag and track' genetic processes

(Phys.org) -- In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material ...

How E. coli cells work in the human gut

(Phys.org) -- The bacterium Escherichia coli, commonly known as E. coli, has a duplicitous reputation. Scientists tell us that most strains of the microbe live peacefully in our guts or the guts of other mammals, munching ...

Programmable DNA scissors found for bacterial immune system

(Phys.org) -- Genetic engineers and genomics researchers should welcome the news from the Lawrence Berkeley National Laboratory (Berkeley Lab) where an international team of scientists has discovered a new and possibly more ...

Jarid2 may break the Polycomb silence

Historically, fly and human Polycomb proteins were considered textbook exemplars of transcriptional repressors, or proteins that silence the process by which DNA gives rise to new proteins. Now, work by a team of researchers ...

Star Wars-inspired bacterium provides glimpse into life

(PhysOrg.com) -- A bacterium whose name was inspired by the Star Wars films has provided new clues into the evolution of our own cells and how they came to possess the vital energy-producing units called mitochondria.
