A very clear explanation of a very complex subject. -- In transcription, the genetic code of DNA is copied into a molecule of RNA. In translation, the information coded in mRNA is used to assemble a specific amino acid sequence forming a polypeptide. -- Help students understand the specifics of and the differences between these two important but sometimes difficult to understand genetic concepts. -- This informative presentation begins with an examination of the early work of Garrod and the Neurospora experiments of Beadle and Tatum which lead to the promulgation of the one gene - one enzyme, and one gene - one polypeptide hypothesis. The structure of DNA and RNA is revealed. -- Colorful, detailed animations demonstrate and explain the functions of RNA polymerase, messenger RNA, mRNA processing in eukaryotes, amino acid attachment to tRNA, polypeptide elongation, termination and more. |
