Do you recognize this model? It represents a DNA molecule. DNA is the molecule that carries genetic information in virtually all living cells. It can also act as a switch.

The Back Story

  • Scientists have figured out a way to turn DNA inside cells into a biological transistor. A transistor is an electronic device that acts like a switch, turning electricity on or off.
  • A biological transistor also acts like it switch. But it turns something other than electricity on or off. Watch this short video to learn more about it:

Read about the DNA switch at the link below. Then answer the questions that follow.

  1. Electronic transistors regulate the flow of electrons along metal wires. In a computer, this determines how calculations are processed. What does a DNA transistor regulate?
  2. What is a possible real-world application of DNA switches?
  3. The scientists are also trying to create the biological equivalent of the Internet. What would this require?
