Human genome 'more active than thought'

Help

The most detailed study yet of the human genome, involving the work of more than 400 scientists in 32 laboratories across five countries, has been published.

The research suggests that far more of the genetic code - some 80% of it - is active in creating and maintaining the human body.

Previously it was thought only a tiny amount of our DNA was functional, leading to the rest being termed "junk DNA".
