The gene synthesis company DNA2.0 has provided direct access to a collection of biological building blocks characterized by the BIOFAB. Gene Designer is free graphically-rich computer-aided design tool that enables bioengineers to easily manipulate and visualize DNA elements such as promoters, terminators, fusion tags and vector components. BIOFAB DNA parts are now embedded within the application. This provides the first “app store” for molecular biology and biotechnology. By embedding a marketplace of third-party, pretested parts, the process of creating optimized or novel genes can be enhanced. Further, the creation of a marketplace offers the scientific community a place to develop and share new biological parts. For more information see: https://www.dna20.com/ and http://biofab.org
