WHEN you're researching something as intricate and complex as human DNA, sometimes you just need luck.
A pair of studies published in the Science and Proceedings of the National Academy of Sciences journal has found human DNA actually has a lot in common with baker's yeast, of all things.
Specifically, your common loaf of bread may contain, along with your Vegemite or preserve of preference, a mechanism that helps DNA copy itself.
The studies have visualised a molecular complex in both human DNA and yeast that keeps parts of the replication machinery from falling off the DNA strand.
Researchers say that at least 40 different diseases, including cancers and some rare conditions, have been linked to problems with DNA replication.
So perhaps your morning slice of toast could one day lead to all kinds of health advancements.
