The likeness of an offspring to its parents, whatever the species, has been traced to a unique molecule that controls the production of proteins and transmits characteristics. This genetic material, dioxyribonucleic acid, or DNA--the hereditary material of life--is described and illustrated in this film by colour animation. Mutations are also discussed. A film for science students.
