TX-TL (short for transcription-translation) is a technology for prototyping biological circuits using cell extracts. The video below shows the core processes of transcription and translation, which are implemented in the TX-TL cell-free system.

By mixing fragments of DNA into TX-TL, we can make use of biological processes to express genes and implement logical functions such as repression and activation.

As an example, we can use multiple fragments of DNA to implement a logical "AND" gate. This gate (or switch) will turn on the expression of a protein only if two input signals are both present.
