Lego-like DNA bricks are child’s play | Chemistry World

Lego-like DNA bricks are child's play | Chemistry World - DNA building blocks have been pieced together to form a multitude of Lego-like bricks by researchers at Harvard University and Massachusetts Institute of Technology in the US. The bricks are nanoscopic but can be locked together like children's Lego blocks and have been used to create more than one hundred distinct shapes with complex surfaces, as well interiors with pores and tunnels.(10.1126/science.1227268)

Ancient genetic systems

Scientists discover possible building blocks of ancient genetic systems in Earth's most primitive organisms - Scientists believe that prior to the advent of DNA as Earth's primary genetic material, early forms of life used RNA to encode genetic instructions. What sort of genetic molecules did life rely on before RNA?(10.1371/journal.pone.0049043)

3D DNA machine

Researchers unveil 3-D structure of 'molecular machine' that initiates DNA transcription - A 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.(10.1126/science.1227786)
