Optimization of protein synthesis for efficiency is thought to be highly important for evolutionary fitness. Watch and listen as Yitzhak Pilpel and Tamir Tuller take you on a brief, personalized tour of their findings that mRNA codons are distributed along the length of the message in a manner that modulates ribosome speed during translation. The ribosome "traffic pattern" generated by conserved codon distribution might minimize cellular energy expenditure.
