Assemble genetic circuits from biological parts. Drag promoters, coding sequences, and terminators onto the DNA backbone, then wire regulatory connections to match target protein expression curves.
Click parts in the palette (left) to select, then click a slot on the DNA backbone to place them. Parts: Promoter (drives expression), RBS (ribosome binding), CDS (coding sequence — makes protein), Terminator (stops transcription). Click "Run Circuit" to simulate.
Synthetic biology applies engineering principles to biology — designing and building new biological systems from standardized genetic parts. Like electronic circuits use resistors and capacitors, genetic circuits use promoters, ribosome binding sites, coding sequences, and terminators. These parts can be combined to create biosensors, logic gates, and metabolic pathways for applications from biofuel production to disease diagnostics.
