Scientists observe single gene activity in living cells

Researchers at Albert Einstein College of Medicine of Yeshiva University have for the first time observed the activity of a single gene in living cells. In an unprecedented study, published in the April 22 online edition ...

Our genes can be set on pause

New evidence in embryonic stem cells shows that mammalian genes may all have a layer of control that acts essentially like the pause button on your DVR. The researchers say the results show that the pausing phenomenon, previously ...

Scientists crash test DNA's replication machinery

(PhysOrg.com) -- Important molecular machines routinely crash into one another while plying their trades on DNA. New research shows that the enzymes that copy DNA before cell division, called replisomes, are the kings of ...

Researchers capture never-before-seen view of gene transcription

Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a node known as the transcription ...
