Synthetic Biology

Designing and building new biological systems.

Synthetic biology treats living things a little like machines that can be designed: scientists build new genetic parts and circuits.

Synthetic biologists build gene circuits such as switches and oscillators, engineer microbes to make useful molecules, and design minimal cells.

The field applies design-build-test cycles, DNA synthesis and modeling to engineer predictable behavior in cells, under biosafety and biosecurity oversight.

Big questions

  • Can we design a living cell from scratch?
  • How do you build a genetic clock?
  • How can engineered organisms be kept safe?

Key ideas

Open any idea in the knowledge graph to see what it connects to, here and in other fields.
  • Technology or method

    Gene circuits

    Engineered networks of genes that behave like switches or clocks. Landmark examples were built in bacteria in 2000.

  • Idea or model

    Minimal cell

    A cell stripped to the fewest genes it needs. One synthetic version runs on 473 genes, 149 of which had unknown functions.

    Emerging research
  • Technology or method

    Metabolic engineering

    Rewiring a microbe's chemistry to make useful molecules, such as a precursor of the antimalarial drug artemisinin in yeast.

  • Technology or method

    Recombinant DNA

    DNA joined from different sources, the starting point of genetic engineering and of medicines such as recombinant insulin.

  • Ethics and safety

    Biosafety

    Risk-based practices and containment that protect people and the environment when working with biological agents.
