<p>What is the difference between the two?</p>
<p>biochemistry focuses on how atoms, electrons, and molecules work in a biological system. A molecular biologist would identify molecules in X process, and try to figure out how they interacted to perform things at the cellular level.</p>
<p>Biochemistry is more of a micro study, where as molecular biology is more on the macro level. Biochem is a bit more math intensive, and you’ll probably need more physics/math classes over bio (and, of course, more bio). They are similar enough though.</p>
<p>biochemistry typical focuses on proteins and metabolism.</p>
<p>Molecular biology often focuses on DNA/RNA, transcription, translation</p>
<p>Cell biology tends to focus on eukaryotic cells and culturing, identification, the cell cycle.</p>
<p>There is huge overlap in all these disciplines. Protein biochemists often do tons cell bio and mol bio work.</p>
