According to this story in The Independent, researchers have created artificial human chromosomes in mice—a breakthrough that may one day be used to treat people suffering from genetic diseases. As part of the new research, genetically-engineered mice had every cell in their bodies replaced with synthetic human chromosomes that were “made from scratch.” Natalay Kouprina of the US National Cancer Institute, one of the scientists that took part in the project, told the paper, “Potentially it has applications for gene therapy, for correction of gene deficiency in humans. It is known that there are lots of hereditary diseases due to the mutation of certain genes” …
