And strikingly, the team found that it did: the human SMC protein cohesin does indeed not only pull DNA into a loop, but also twists the DNA in a left-handed way by 0.6 turns in each step of ...

If measured from beginning to end, the DNA in our cells is too long to fit into the cell’s nucleus, explaining why it must be constantly folded and packaged. When it is time for cell division, and the ...
