Cracking DNA for students
Category : Molecular Structure Talks
Alberto Lesarri gave a talk at the “Diego de Praves” Secondary School in Valladolid last February 2, replicating the 1950’s DNA X-ray diffraction experiment with a laser pointer and a light bulb. This demonstration experiment basically shows the diffraction of an helix, giving opportunity to talk of the experimental work of Rosalind Franklin, as explained in 2018 in the American Journal of Physics.
You can compare the pointer diffraction, with the real pattern below:
