Summary
Designing and building new biological parts, circuits and organisms with engineering principles.
In depth
BioBricks standardise parts; iGEM competitions. Milestones: toggle switch, repressilator, synthetic yeast chromosomes (Sc2.0) and the minimal cell JCVI-syn3.0 with 473 genes. Applications include biosensors and cell factories.
Design-build-test-learn cycles use standard parts and computer models. Cell-free systems allow rapid prototyping. Biosecurity and biosafety are central considerations.
Example: minimal genomes help identify essential genes.
Synthetic biology applies engineering principles such as standard parts, modularity and design-build-test cycles to living systems. It builds genetic circuits (switches, oscillators, sensors), redesigns metabolism, and even synthesises whole genomes.
Landmarks include the repressilator oscillator in E. coli, the minimal bacterial cell JCVI-syn3.0 with 473 genes, and synthetic yeast chromosomes. Parts are shared in registries such as BioBricks. Applications include biosensors, programmable cell therapies and bio-based chemicals.
Example: engineered bacteria that change colour in the presence of arsenic in water.
Frequently asked questions
What is Synthetic Biology?
Designing and building new biological parts, circuits and organisms with engineering principles.
Which area of biology covers Synthetic Biology, and how advanced is it?
Synthetic Biology is one of the 56 topics in Biotechnology & Genomics. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Biotechnology, Biobanking and Data Privacy, Systems Biology.
Why does Synthetic Biology matter?
It raises biosecurity and ethical issues, as well as opportunities, since living cells are noisy, evolve and are harder to engineer than machines.
Can you give an example of Synthetic Biology?
Engineered bacteria that change colour in presence of arsenic.
What should I learn before Synthetic Biology?
Work through the Beginner topics in Biotechnology & Genomics first, such as Biotechnology, Genetic Engineering, Selective Breeding, then return to Synthetic Biology. Advanced topics assume the Intermediate vocabulary.
What topics are related to Synthetic Biology?
The closest topics to Synthetic Biology are Biotechnology, Biobanking and Data Privacy, Systems Biology, Machine Learning in Biology. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand Synthetic Biology?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Synthetic Biology. To practise the whole of Biotechnology & Genomics, use the Biotechnology & Genomics quiz.
How is Synthetic Biology different from Biotechnology?
Synthetic Biology: Designing and building new biological parts, circuits and organisms with engineering principles. Biotechnology: The use of living organisms or their parts to make products or solve problems. Read both side by side and note what each one explains.
How should I study Synthetic Biology step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Biotechnology and explain the difference aloud. Finally, take the Biotechnology & Genomics quiz and come back to this page for any question you miss.
