13 Lack of Standardisation The lack of standardization in assembly techniques for DNA sequences forces each DNA assembly reaction to be both an experimental tool for addressing the current research topic, and an experiment in and of itself. One of our goals is to replace this ad hoc experimental design with a set of standard and reliable engineering mechanisms to remove much of the tedium and surprise during assembly of genetic components into larger systems Tom Knight, MIT. from Idempotent Vector Design for Standard Assembly of Biobricks, Tom Knight (MIT) 2003.
