Structure and operation of the coded chromosome message that controls the organization of all life. Features building the DNA molecule from sugars, phosphates and the bases; transcription of mRNA; amino acid codes; protein synthesis via tRNA; mutations and simulation of their effects. Extensive graphics and interaction.

Includes the base sequences of two actual genes plus option to enter a custom gene. Mutation by point, addition or deletion can be made to any part of gene. Then normal and mutated genes are compared through: DNA-promoter-RNA-amino acid sequence and protein fold structure.
