Yep. In 2017 a bunch of us spent heaps of time the night before going through specific immunity and then didn't get any short answer questions on it haha

Was there anything surprising?

I've heard that from a lot of people. Bit surprising given people did quite a bit better on the 2018 exam than the 2017 exam. Would have expected this one to be at least as difficult as 2018 again.

Definitely much easier than 2017 and 2018. Didn't stop me from messing up on expression throughout the paper however  ;D

I wrote something about the constant region of antibodies being similar and the differences in antigen binding site being very minute and small... probably wrong though.

Funnily enough, found it much harder than 2017 and 2018. I made some silly mistakes...

What was the one where they transcribed the structural gene and it said what molecule does it make?
Options were
Repressors
Transcription factors
Lactose
mRNA

I said that the environmental temperature was not controlled, so it could be fixed by doing the experiment in a room with a controlled temperature.
