Genetics is one of the priority areas of modern biology. The purpose of the book "Practical Molecular Genetics for Beginners" is to acquaint schoolchildren with this science, its achievements and the application of these achievements in everyday life, with professions related to genetics. The peculiarity of this course is a large number of practical tasks and role-playing games, which are designed to clearly demonstrate the laws and methods of genetics and molecular biology. Theoretical and practical classes are proposed to be held both in the school office and in the laboratory.
