Teenage scientist Fred Turner constructs 'DNA photocopier'

Help

A 17-year-old scientist from Yorkshire has built his own DNA testing machine and is using it to conduct experiments in a laboratory at his home.

Fred Turner built the machine, known as a Polymerase Chain Reaction machine, at a cost of just £250 - much lower than the several thousand pounds it would have cost to purchase.

Examining DNA cells is highly complex work and Fred's efforts have been rewarded with both a top engineering prize and a place to study biochemistry at Oxford University.
