Brewer's yeast, one-third of whose genome is said to share ancestry with a human's, has 16 chromosomes. However, Chinese scientists have managed to fit nearly all its genetic material into just one chromosome while not affecting the majority of its functions, according to a paper released Thursday on Nature's website. Qin Zhongjun, a molecular biologist, and his team used CRISPR-Cas9 genome-editing to create a single chromosome yeast strain, the paper said. (Xinhua/Ding Ting)
