To know, what is the difference between biochemistry and biology we have to get deeper into the branch of biochemistry. It has 4 major branches such as cell biology, molecular biology, metabolism, and genetics. In biochemistry, cell biology focuses on the eukaryotic organism instead of a prokaryotic organism. It studies the cell and its signalling pathways within the body. Then comes molecular biology, the root of biochemistry which defines the interactions between DNA, RNA, proteins, and their synthesis. Metabolism is another crucial topic that deals with the transformation when food gets converted into energy in the human body. Finally, comes the genetics that studies the genes and their heredity characteristics in the organisms.
