DNA Assembly and Cloning

DNA assembly and cloning are critical techniques in synthetic biology that enable researchers to create and modify DNA sequences for various applications, including gene editing, protein engineering, and synthetic biology. Traditional cloning methods, such as restriction enzyme digestion and ligation, can be time-consuming and often result in unwanted mutations or errors. However, recent advancements in DNA assembly and cloning techniques have enabled researchers to construct complex DNA sequences with greater speed, accuracy, and efficiency.

Biocontainment Strategies in Strains

In the field of synthetic biology, genetically modified organisms (GMOs) have been engineered to produce a variety of products at an industrial scale. However, concerns have been raised surrounding the ecological risks associated with the release of GMOs outside of controlled environments. Biocontainment systems are needed to neutralize these GMOs and prevent them from causing harm to the environment. In addition, alternative selection markers are needed to replace costly and risky antibiotics.

Key advantages of cellular and cell-free bioproduction.
