Genetic engineering and protein synthesis.

Introduces the principles of genetic engineering and explains the major steps in protein synthesis. Part One explains how the genetic information in DNA is responsible for the synthesis of specific proteins. The processes of transcription and translation are clearly demonstrated and explained. Part Two provides a step-by-step explanation of the processes of genetic engineering - i.e. how the protein manufacturing process within the cell can be manipulated to enable the cell to manufacture proteins useful to man.
