Genetic switch?
Scientists used DNA to build biological switches called transcriptors, which act like transistors found on computer chips.

Computers are lifeless. They?re ordinarily built from metal,
silicon, plastic and other materials. Those components work together to shuttle
around the electricity needed to surf the Internet, watch videos or even do
homework.
But why stick to the ordinary? Scientists are finding that
computer parts can also be built from DNA. This long molecule contains genetic
material and is found inside almost every living cell. It tells each cell which
molecules to make. In March, researchers published a study that shows how DNA
also can be used to build an important computer component, called a transistor.
