 What happens is they untwist like this and then they become more planar instead of twisted. They become more planar with each other. Some mechanics. Nobody knows how many cells are in human body. There's hugely varying estimates. But in the blood bone marrow, in our bone marrow which produces blood cells, red and white blood cells, there's 500 million blood cells born every minute in your life. 500 million. Now see the details of how the DNA is sitting inside the channel. So this is a spring that's about to spring and that movement forces the DNA, twisting the DNA to actually locally unwind in the middle. That's our model.
