- 15.1.2: Central Dogma- DNA to RNA to protein
- A few years after he and James Watson had proposed the double helical structure for DNA, Francis Crick (with other collaborators) proposed that a less stable nucleic acid, RNA, served as a messenger RNA that provided a transient copy of the genetic material that could be translated into the protein product encoded by the gene. Such mRNAs were indeed found. These and other studies led Francis Crick to formulate this “central dogma” of molecular biology.
- 15.1.3: Transcription and mRNA structure
- Several aspects of the structure of genes can be illustrated by examining the general features of a bacterial gene as now understood.
