M2 PRESSWIRE-12 October 2000-US NSF: Putting muscle in the nucleus (C)1994-2000 M2 COMMUNICATIONS LTD RDATE:12102000 Scientists have long pondered how, inside the nucleus of a cell, long stretches of DNA are moved through the huge enzyme factories that transcribe DNA's genetic information into messages made of RNA.

Now, for the first time, a team of scientists from the University of Illinois at Chicago has demonstrated the presence of a "molecular motor" inside the nucleus, where it appears to power the assembly line that forges RNA messages off of the long DNA templates. The finding is reported in the Oct. 13 issue of the journal Science. The work was funded by the National Science Foundation (NSF), the National Institute of General Medical...
