Yehuda Ben-Shahar and his team at Washington University in St. Louis have discovered that some mRNAs have a side job unrelated to making the protein they encode. They act as regulatory molecules as well, preventing other genes from making protein by marking their mRNA molecules for destruction.
Nobel Prize-winning biologist Sydney Brenner will deliver the annual Arthur Holly Compton Memorial Lecture for the Assembly Series at 4 p.m. Tues, Oct. 14. The lecture,”Humanity’s Genes,” is free and open to the public and will be held in Graham Chapel, located just north of Mallinckrodt Center (6445 Forsyth Blvd.) on the Washington University campus. Brenner’s lecture will discuss some of the questions raised by the completion of the Human Genome Project. He will talk about both the benefits and the fears raised by recent breakthroughs in genetic research, and his belief that the brain is mightier than the genome.
