Scientists unveil 3-D structure of 'molecular machine' that initiates DNA transcription after 3 decades of searching

Scientists unveil 3-D structure of 'molecular machine' that initiates DNA transcription after 3 decades of searching: "An team of Rutgers University scientists led by Richard H. Ebright and Eddy Arnold has determined the three-dimensional structure of the transcription initiation complex, the key intermediate in the process by which cells read out genetic information in DNA."
