  <dc:title>Letter from James D. Watson to Francis Crick</dc:title>
  <dc:subject>RNA</dc:subject>
  <dc:subject>DNA</dc:subject>
  <dc:description>Watson here gave details about his X-ray studies of the structure of RNA (ribonucleic acid), the single-stranded companion molecule to DNA which is an essential intermediary in protein synthesis. His warning that &quot;it will be a nasty job to prove existence of 20 specific cavities&quot; in RNA (p.3) was a reference to George Gamow&apos;s idea that genes could provide a direct, physical template for the twenty amino acids that form the polypeptide chains of which proteins are made up..
