Science Citation Classic: Beadle And Tatum

Behind every major scientific effort is a story. Beadle and Tatum's story is one of persistence. They began with a hypothesis: each gene causes the production of a single enzyme, and that enzyme catalyzes a biochemical reaction within an organism. The ...

MiR-96 Gene Implicated In Progressive Hearing Loss

In parallel human and mouse studies, two groups of researchers have come to the same conclusion: that a new kind of gene is associated with progressive hearing loss. The new gene, a microRNA, is a tiny fragment of RNA that affects the production of hundred ...
