Biological computer closer due to DNA transistor

Biological computer that ‘lives’ inside the body comes one step closer as scientists make transistor out of DNA and RNA – Science – News – The Independent.

Finding could lead to new biodegradable devices based on living cells that are capable of detecting changes in the environment

 

Scientists believe they are close to building the first truly biological computer made from the organic molecules of life and capable of working within the living cells of organisms ranging from microbes to man.

The researchers said that they have made a transistor – the critical switch at the heart of all computers – from DNA and RNA, the two biological molecules that store the information necessary for living things to replicate and grow.
