<p>Hey there, I’m a junior in chemical engineering.</p>
<p>1) Those kinds of classes can usually count for ChE elective requirements, depending on the program. For instance, I’ve been taking upper-division biochemistry and bioengineering courses as electives for ChE.</p>
<p>2) Very relevant. I’m currently taking a class, ChE 130: Biomolecular Engineering, where we do just that. I also do research in a ChE lab where I’m basically engineering proteins to incorporate non-natural amino acids into cellular proteins using the methods you just described above.</p>
<p>I’d be happy to answer any more “stupid” questions.</p>
