What better way to celebrate the 60th anniversary of the publication of Watson and Crick's landmark paper on the double helix structure of DNA than by making your own double-helix out of jellybabies and licorice? Dr Mark Lorch's method for making edible DNA models promises to capture the "elegant simplicity" of DNA.
Two long, flexible sweets, such as liquorice ribbons.
A few handfuls of soft, highly coloured sweets, such as jelly babies or marshmallows.
For advance bio-engineers, Lorch also explains how to extract the DNA from a kiwi fruit using things lying around your kitchen.
How to make a DNA double helix from jelly babies and liquorice [Dr Mark Lorch/Guardian]
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
