By harnessing a unique property of yeast, scientists can synthesize histones and the enzymes that modify these proteins, which spool DNA and influence gene expression.
Over centuries of cultivating Saccharomyces cerevisiae to make dough, bakers have put selective pressure on the species, causing it to diverge into two distinct groups, according to the authors.
Two studies contest the idea that the noncoding sequences are just “junk DNA,” demonstrating that they play important roles in the regulation of cell growth.
With multiple applications in biomedicine, the antibodies can now be made quickly, cheaply, and without the need for an alpaca or one of its relatives.
