[Origins of molecular life sciences. Polish context].

Different scientific disciplines such as physics, genetics or biochemistry crossed over into molecular biology in the last century. The Polish state didn't existed at the beginning of XX century, but the territory for a large number of scientists was not a limitation in delineating new routes, making fundamental discoveries or training the new generation of distinguished people of sciences. We want to tell the story of roots of molecular biology from the Polish perspective and outline its importance, by bringing closer the most essential discoveries of elite scientists in different fields of life science, associated with Poland and its territory.
