Translating the code protein synthesis

Uses animated graphics to clarify the complex processes of genetic coding and protein synthesis. It helps students understand biology's central dogma, "one gene-one protein", and investigates some notable exceptions to that rule, particularly Tonegawa's Nobel Prize-winning solution to the problem of antibody diversity.

  • "A dynamic presentation of the current state of knowledge of the genetic code. Combines a clear and concise illustration of the basic elements comprising the Central Dogma of molecular genetics with fascinating examples of notable exceptions to the rule."
  • "Presents key concepts in molecular genetics. Part 1 discusses currently accepted biological theories on protein gene codes (one per protein) and the nature of cell renewal & construction (DNA to RNA to protein). Part 2 looks at challenges to accepted theory such as Nobel Lauriate Susuma Tonegawa's examination of antibody proteins which outnumber genes."
  • "Part 1:compares cells to factories which manufacture all the proteins that an organism needs. It describes the code that directs these cellular factories to produce the right proteins at the right time: from chromosomes to the molecular structure of the DNA and how the discovery of this structure provided the key for unlocking many of the mysteries about how the genetic code operates. Computer graphics clarify the various steps of protein synthesis. The section ends with a discussion of biology's central dogma, which holds that one gene codes for one protein and that genetic information always flows in one direction: from DNA to RNA protein. Part 2: looks at challenges to this central dogma. It describes Nobel Laureate Susuma Tonegawa's solution to the problem of how the body can make more antibody proteins than there are genes. Tonegawa showed that the genes can be rearranged so that they can code for different proteins. Part 2 also shows that retroviruses, such as the AIDS virus, challenge the usual assumption that DNA always codes for RNA. Another Nobel Laureate, Barbara McClintock, further challenged conventional thinking by showing that DNA can be influenced by environmental factors and that proteins can pass."
