摘要
Artificial chromosomes are DNA molecules of predictable structure, which are assembled in vitro from defined constituents that behave with the properties of natural chromosomes. Artificial chromosomes were first assembled in budding yeast and have since been useful in many aspects of yeast genetics. Several attempts have been made at building artificial chromosomes in mammals, although these have been met with limited success. Consequently, mini-chromosomes of defined structure have been developed to address questions regarding mammalian chromosome function and for biotechnological applications. Here we review progress in these areas and consider how it influences plans to build artificial chromosomes in plants and parasites.
