If you took the DAT, must we memorize the structures of nucleic acids?

I'm currently using the Kaplan online quizzes and I came across this question (see screen shot below) and I was wondering if on the OChem section I would need to recognize structures such as the purines and pyrimidines? I know the DAT expects us to know the structures of ketones, carboxylic acids, etc, but I'm referring to the structures of organic molecules much less focused on such as these.

Hey, I haven't taken the DAT yet so I can't really answer your question but pyrimidines and purines show up in DNA structure so it might be in our best interest to be able to recognize those for both the bio and orgo sections!

Yeah memorize them, also know the basic organic compounds as well: toluene, phenol, aniline, formaldehyde, etc.

I know that A-T pairings have 2 H bonds and G-C pairings have 3 H bonds and that's as far as the extent of those structures I thought we would need to know. Oh, well. Time to memorize more structures

Haha, I took biochem this spring so thankfully that's one thing I don't have to spend time memorizing! To be honest though, I just remember that purines are double rings and pyrimidines are single rings and that they have some N scattered around. 😛

yup, I remember it as longer words are smaller and shorter words are longer.
