Video: DNA strand cut in two using 'molecular scissors'
Japanese researcher Hiroshi Nishimasu has shared a video which shows the CRISPR/Cas9 gene-editing technique to cut through a DNA strand. The yellow blob shows the DNA-cutting enzyme Cas9, which cleaves the brown-coloured DNA strands. CRISPR has so far been used to change flower colour, eliminate HIV in animals, and remove a gene that causes heart disease, from human embryos.
