"It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code"

This quote by Francis Crick is referring to the genetic code, which is the set of directions that tells cells how to make proteins. Crick is stating that while there is indirect hereditary evidence that suggests the code is a triplet code, implying that three nucleotides in a row make up one code, it has yet to be proven by direct biochemical approaches. This means that the evidence has actually not been acquired through experiments that straight determine the biochemical homes of the code. Crick is recommending that further research is required to verify that the code is indeed a triplet code. This research study could include experiments that measure the biochemical residential or commercial properties of the code, such as the rate of protein synthesis or the rate of transcription. By conducting these experiments, researchers can acquire a much better understanding of the genetic code and how it works.
