Transcriptional features of fractionated human breast tumor chromatin
By means of controlled mechanical shearing it was possible to fractionate human breast tumor chromatin in 'active' and 'inactive' species, according to their in vitro template activity, using E. coli RNA polymerase. The 'active' molecules can be resolved in 3 well defin...
