• 

  Hardwires

  Parts whose presence in a gene define expression levels directly.

• 

  Input

  Modulators of gene expression based on external inputs, in the form of small molecules, light, or metals.

• 

  Buffer Gates

  Parts activated by regulators, with ascending response functions.

• 

  NOT Gates

  Parts repressed by regulators, with descending response functions.

• 

  AND Gates

  Systems with separately-expressed parts that won't work independently.

• 

  Insulation

  Sequences with no regulation or change to expression levels, but serve to isolate parts' funcions from genetic context, improving modularity.

• 

  Vectors

  Components of the backbone surrounding a circuit. Could also function as a hardwire.

• 

  Communication

  Regulation between cells, based on quorum sensing autoinducers.

• 

  Memory

  Parts for systems where a temporary input can set a constant memory output.

• 

  Output

  Endpoints of a circuit. Normally reporters or systems that regulate a gene of interest.
