The genetic code is the system that organisms use to store and encode information required for life. The cellular molecular machinery transfers the genetic information from DNA or RNA genomes into translatable messenger RNA and proteins. The triplex code is familiar to all biologists and utilized by gene therapy researchers. Marshall Nirenberg, a post-doctoral researcher at the National Institutes of Health, envisioned the basis for the genetic code in the late 1950s and by 1965, determined the RNA code for each amino acid. In 1968, Marshall Nirenberg was awarded the Nobel Prize for Medicine or Physiology.
