There are many genes, or at least markers of one sort or another within our DNA sequences, that have been associated with height. By some estimates the number could be thousands. However, finding those select genes that have ...
A team of physicists working at the intersection of theory and experiment are shedding new light on the "teamwork" of molecular motors—called RNA polymerases (RNAPs)—that mediate DNA transcription. During transcription, ...
