Very easy lab course. Lots of downtime and never really in a rush. Easy to leave early if you're well-prepared and/or have previous experience doing this for a co-op. Worst part would be having to work on a research project development/proposal throughout the term.

Very fun course, depends a lot on the TAs you get as you spend a lot of time under their instruction. Laura is very knowledgeable and kind. Exams are very easy with a bit of studying and the final project feels like real research compared to other lab reports. Highly recommend to anyone going into bio research.

REALLY useful wet labs. The major techniques covered are: making and performing gel electrophoresis from scratch, Safeview gel imaging, DNA purification and analysis, PCR, DNA RE digestion + ligation to a vector, cell transformation (heat shock and electroporation), protein SDS electrophoresis, protein western blotting/probing. These techniques will be extremely useful for coops and research positions. The course grading is: lab performance (20%), lab quizzes (3%), lab notebook checks (20%), experimental design proposal (12%), 2 midterms (20% and 25%). The experimental design proposal is done with your lab partner. You are given a research scenario/prompt and will follow weekly milestone…

6 hour lab. Very useful! Learn to set up/run agarose and SDS PAGE gels, western blots, make your own petri dishes, transform bacteria with recombinant plasmids, etc.

Loved the lab, loved the course. Very very useful in the real world.

“Is anyone else enrolled in any courses you find exciting next semester? I'm super excited about a few of mine next term.”
u/VenomRex: “what are the exciting courses you are talking about?”
[deleted]: “For me, they're exciting. It's virology (biol 442), molecular biology techniques (biol 335l) and advanced immunology (biol 441).”

BIOL 335L VS CHEM 335L 1 point, 6 comments
u/RonaSeason123: “I'm looking to do one or the other but don't know which lab is more useful for jobs in the pharmaceutical industry. Any insight would be helpful! FYI, I am a medicinal chemistry student.”
u/b266curve: “Not sure if you are looking into taking one of them this fall, but BIOL 335L is not offered for the Fall 2020 term (it was cancelled). It is offered in the winter though! I can't find any information about CHEM 335L, however.”
u/boyidgaf: “Take both if you can, but Chem 335L might be a bit more relevant.”
u/RonaSeason123: “I have to fit Chem 357 into my schedule to take Chem 335L. If I can only take Biol 335L would that still be good tho? If not then I can squeeze Chem 335L.”
