Hey Biochemians! As we have come to the end of this Biol 1362 course and final exams are right around the corner I thought what better way to end this blog than with a summary to help everyone study. At the end of studying a topic I like to answer all the learning objectives for that topic without using any resources. Then I like to mark it and critique my answer using a fine tooth comb lol. It really helps me so I hope this helps you guys too. Below I have attached all the learning objectives for each topic studied. Happy Studying!
