Researchers have used yeast to learn more about how satellite (extrachromosomal) DNA circles are formed to carry amplified genes, how the gene duplication is specific to the environmental pressure and the effects of age. Understanding the mechanism of gene duplication and DNA circle formation has relevance to the biology of ageing and the development of drug resistance in cancers cells.
