Molecular biology is one of the most interesting sciences, in which new discoveries are made every day. Initially arising at the intersection of such disciplines as biochemistry, genetics and physics, molecular biology was able to lay the foundation for many interesting achievements of modern engineering mind, which brought an invaluable contribution to the development of medicine, agriculture, and cutting-edge technologies. It studies the structure and properties of proteins and nucleic acids as well as various molecular mechanisms underlying biological processes and the life itself.
