<p>Good points, kasiaaa. </p>
<p>The molecular bio major requires general and organic chem. Orgo is a prereq for the intermediate courses (for examples, genetics and biochem). Typically, amongst molecular bio majors, gen chem and orgo are taken during the first and second years, respectively (whereas, many bio majors may take intro bio in their second year). After orgo is completeled, genetics and biochem are usually taken in the junior year.</p>
