Israeli scientists use 'laser tweezer' to study DNA mystery - study
Using optical tweezer technology, Technion researchers were able to gain a greater understanding of the poorly understood DNA packaging process, which impacts how genes are expressed.
Optical tweezers apply force on DNA, and "unzip" it into two separate strands. Upon reaching the chromatosome the unzipping is halted by contacts of the histone proteins (yellow, pink, blue) with the DNA, revealing whether the chromatosome is in an "open" (right) or "closed" (left) structure.(photo credit: TECHNION)ByJERUSALEM POST STAFF
