...J. Rutgers scientists have deciphered the complex mechanics of microcin J25 (MccJ25), a tiny, natural molecule that acts like a cork in a bottle to block a key bacterial enzyme potentially leading to a new generation of antibiotics. Two teams of researchers at Rutgers, The State University of New J...Proteins transform DNA into 'molecular velcro'
... of housekeeping processes in chromosomes, but the mechanics behind their function have been largely unknown. When the researchers alternately stretched and compressed a single molecule of DNA with condensins attached, they found that the DNA extended in stepwise "clicks," akin to Velcro unzipping.
