Alice gave a sold out out talk at London’s ‘Atoms to Galaxies’ Pint of Science event. If you missed it, the abstract is below:

Did you know that the DNA in each of your cells is taller than you are? You have around 2 metres of DNA packed into every cell of your body, and given that you have around 30 trillion cells in your body, that means you have enough DNA to wrap around the earth over a billion times! This DNA has to be compacted into the cell nucleus, which is only a tenth of the width of a human hair. From this highly compacted bundle, DNA is continually unravelled, read, and copied, which can result in knotted, tangled, and twisted structures. I use a microscope which ‘feels’ the surface of DNA molecules to see these complex structures with a 1,000,000,000X zoom.
