(2) King C.C., (1982), A Model for the Development of Genetic Translation Origins of Life, 12 405-417. Several models have been advanced for the development of the genetic code and translation apparatus. Eigen in particular has put forward a detailed model based on the hypercycle. This paper uses some of these previous ideas to develop a new model of the code and translation in which the pairs AU and GC play complementary roles, and in which tRNAs develop from a molecule with two loops which stacks in repetitive pattems without the need tor a messenger RNA. Thus a bridge is provided between random. (or autocatalytic) polvmerization, and coded translation. In addition, altemative postulates to several of Eieen's ideas are tested bv computer simulation.
