Dance of DNA at Science Museum

Switch To A Different You?

By Dr Corrinne Burns, Assistant Content Developer

Do you look like your parents? Do you have your mother’s green eyes, or your father’s freckles? We’re so used to thinking of physical traits in terms of genes – genes for height, genes for eye colour, even genes for baldness. But new research reveals that your genes are only a tiny part of what makes you, you. In our new display case, Switch To A Different You? – the Science Museum explores the significance of a groundbreaking discovery.

Switch To A Different You?

Genes make up only around 2% of your DNA. So what’s the rest of it for? We used to think that most of our DNA was junk – but it isn’t. Scientists working on the Encyclopaedia of DNA Elements project – called ENCODE for short – have discovered that, in reality, our “junk” DNA is made up of millions of switches, which act to turn those few genes on and off. Your DNA is, in effect, a gigantic, dynamic, dancing switchboard.

What does this mean for science – and for our sense of identity? If our genes are such a small part of our DNA, then why do we look the way we do? How does our childhood environment influence the behaviour of our genetic switchboard? If we could live our life again, would we look very different? And how will the discovery of this vast genetic switchboard help us to understand – and maybe treat – genetic diseases?

The Museum is celebrating ENCODE’s groundbreaking discoveries in a unique way. Ling Lee, on the science news team here at the Museum, came up with the wonderful idea of visualising DNA replication via an aerial silk dance. So Ling, together with Ewan Birney, one of the ENCODE project leaders, worked with acrobat Michèle Lainé of Viva Aerial Dance to choreograph a spectacular (and scientifically accurate!) performance. Join us on the Who Am I gallery at 1.30 pm tomorrow, Thursday 6th September, to see the dance that Ling and Michele created – and to find out more about the science that inspired the display.

In Switch To A Different You?, we begin to explore the significance of ENCODE’s discoveries. We don’t have all the answers – this science is so new that we don’t yet know where it will lead us. But we want to know what you think. If you could live your life all over again, do you think you’d be the same person you are today?

    Knowing what I now do about life, I would certainly live it differently and if this resulted in my looking different to how I look today, that would be an amazing curiosity… Wonder how this scientific exploration will turn out?
