Laser tweezers
![The optical tweezers on the right begin to unravel the DNA into its two strands. When the primer reaches the chromosome, it will be stopped by contacts between the histones [in yellow, pink and blue] and the DNA, and thus it will be possible to check whether it is an open (bottom right) or tight (bottom left) chromosome.](https://www.hayadan.org.il/images/content3/2021/07/2-2-768x536.png)

One of the main tools in the research is the "laser tweezers" developed at the Technion and which allows the DNA strands to be unraveled in order to examine the connections between them and important molecules that help organize them in the cell nucleus
