FT014 - What is Synthetic Biology?
Summary
TLDRSynthetic biology is an engineering approach to DNA, where scientists apply design principles to create new biological systems or tools. Unlike traditional genetic engineering, which was more of an artisanal process, synthetic biology leverages modern tech like CRISPR, automation, and AI to standardize and quantify biological experiments. The field emphasizes an engineering mindset, focusing on design, build, test, and learn loops, and fosters a community of 'nerds' passionate about integrating engineering with biology.

Q & A
What is synthetic biology?
-Synthetic biology is the engineering design process applied to DNA, where scientists use design principles to construct new biological systems that are interesting or useful, or create new technologies and tools for reading, writing, or editing DNA.
How does synthetic biology differ from genetic engineering?
-While genetic engineering involves the manipulation of genes, synthetic biology goes further by applying engineering principles to design and build new biological systems, focusing on standardization, quantification, automation, and simulation.
What role do synthetic biologists play in the field of biology?
-Synthetic biologists act as scientists seeking design principles for biology, developers constructing new biological systems, or inventors creating new technologies and tools for genetic manipulation.
Why did the term 'genetic engineering' become popular in the 1970s?
-The term 'genetic engineering' became popular in the 1970s as the first DNA technologies were emerging, marking a productive era for biotech with the creation of transgenic mice and recombinant human insulin.
What limitations did early genetic engineering face?
-Early genetic engineering was limited by a lack of tools for working with DNA, such as sequencing technology, DNA synthesis capabilities, measurement tools, and laboratory automation, making it more of an artisanal craft process.
How has the advancement of technology transformed genetic engineering into synthetic biology?
-Advancements in DNA sequencing, synthesis, gene editing tools like CRISPR, omics technologies, laboratory automation, and AI for DNA design have enabled the standardization, quantification, and automation of biological systems, leading to the emergence of synthetic biology.
What is the significance of the 'design, build, test, learn' loop in synthetic biology?
-The 'design, build, test, learn' loop is an iterative process used in synthetic biology that reflects the engineering forward approach, focusing on enabling technology, measurement, and the design process.
What is a 'chassis' in the context of synthetic biology?
-In synthetic biology, a 'chassis' refers to an engineered yeast strain or other biological system that serves as a base upon which genetic circuits or other biological components are built.
What is a 'genetic circuit' in synthetic biology?
-A 'genetic circuit' in synthetic biology is a piece of functional DNA that has been designed to perform a specific task or function within a biological system.
Why is the term 'synthetic biology' important for the community?
-The term 'synthetic biology' is important as it helps to bring together a community of people who share the goal of applying engineering design processes to DNA and seek to find others with similar interests and approaches.
How does synthetic biology relate to computer code?
-Synthetic biologists often debate the similarities between genetic code and computer code, reflecting the field's focus on using engineering principles, including computational tools, to design and manipulate biological systems.
