BCH210 (Second-year life sciences): Looking for online resources

Hello, hello.

I'm a second-year life science student and am struggling a little with biochemistry at the moment. I can understand all the concepts pretty quickly, but I can't seem to memorize stuff like the codon sequences and enzymes. The lectures aren't really all that helpful and the TA office hours don't really help a lot either. Any tips to help with memorization would be greatly appreciated, as well as other tried and tested resources.

​

Thank you!
