• New method knocks out yeast genes with single-point precision

    7 days ago - By Phys.org

    How do you make yeast work harder? Not to make bread, but in processes that yield chemicals and pharmaceuticals. Industries currently use a yeast called Saccharomyces cerevisiae. They'd like it to work better. The answer is in manipulating the yeast's genetic code. To get at that code, researchers developed a method that turns off targeted genes in the yeast, introducing mutations. The team's approach deletes specific points in the DNA sequence. They study how each deletion affects the yeast. Does a deletion cause the yeast to stop working in certain chemicals? Does a deletion make the...
