Origin of chirality: a structural theory.
The molecular basis for the origin of chirality is presented: The complex of the anticodon bases and the discriminator base on a D type tRNA can recognize a L type amino acid. Exceptionally the D type tyrosine can be recognizable by the D type tRNA as shown by Calender and Berg. The advantage of such a stereochemical theory over the frozen accident theory is discussed.
