<span style="color: #222222;">Chinese scientists claimed to have created the first single-chromosome yeast while not affecting the majority of its functions, a breakthrough that could help in furthering research related to aging and diseases in humans. </span><br />'' <br />'' <span style="color: #222222;">Brewer's yeast, one-third of whose genome is said to share ancestry with humans, 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.</span><br />'' <br />'' <span style="color: #222222;">Molecular biologists at the Centre for Excellence in Molecular Plant Sciences in china used CRISPR-Cas9 genome-editing to create a single-chromosome yeast strain. </span><br />'' <br />'' <span style="color: #222222;">Using the CRISPR-Cas9, the research team removed the DNA at the telomeres, the ends of chromosomes that protect them from degrading. They also snipped out the centromeres, sequences in the middle that are important to DNA replication. </span><br />'' <br />'' <span style="color: #222222;">The research may also pave the way for new man-made species in the future.</span><br />'' <br />
