Cell biology, genetics and evolution are fundamental to an understanding of the processes of life. All the basic concepts of the subject will be discussed. From the  structure and function of prokaryotic and eukaryotic cells, including a discussion of biomolecules, mitosis, meiosis and cell cycle, DNA structure and function from molecular to organism levels,  classical genetics,  molecular genetics and  evolutionary theories as unifying explanations of life.
