Modular Assembly of Synthetic Secondary Chromosomes.

The development of novel DNA assembly methods in recent years has paved the way for the construction of synthetic replicons to be used for basic research and biotechnological applications. Questions of how chromosomes need to be constructed to maintain the genetic information can now be answered by a learning-by-building approach. Here, we describe an efficient pipeline for the design and assembly of synthetic, secondary chromosomes in Escherichia coli based on the popular Modular Cloning system (MoClo).
