What is biochemistry, and how does it differ from the fields of genetics, biology, chemistry, and molecular biology?

Biochemistry is very different yet similar to genetics, biology, chemistry, and molecular biology. Biochemistry involves the use of chemistry to explain biological processes as well as studying the structure and the chemical aspect of molecules in living organisms. Chemistry mainly studies the reactivity of these molecules as well as the structure and characteristics of these molecules.  The major difference is that chemistry is not about the living organism; its focus is mainly molecularly. It does not go far on the structural organization of the human body. Genetics is extremely different from biochemistry. It actually studies how characteristics are inherited and not so much about the reactions and characteristics of these molecules.  Biochemistry is also quite different than biology.  Biology is basically the study of life.  It focuses on their behavior, environment, origin, function, and evolution opposed to reactions of these organisms.  Molecular biology is surprisingly quite similar to biochemistry.  Molecular biology also uses chemistry to explain the interactions of the molecules.  It differs mainly in the way that it is interested in the DNA/RNA processes.
         In conclusion, biochemistry has many differences as well as similarities to each of these fields.  They are very similar in the way that some study the human life and some study the chemical reactivity of these molecules.  They are very different in the way that each of these fields do not incorporate both chemistry as well as biology.  They are mainly similar to one of these fields; either biology or chemistry.
