9844719]I kinda flew by the seat of my pants with this, but I used First Aid's "Always Bring Polymerase", "Naked CPR and PAPP smear" and BOAR mnemonics. So, anything that isn't Always Bring is positive strand, positive stand is icosahedral, and negative strand is helical.[/B] There isn't much left after that, it's easier to absorb the actual manifestations of the disease (in my opinion), and I just ignored the circular/linear strand stuff (except for Hep B, 'cause it's weird).
When I actually was taking micro I know that I knew that chart well enough to figure out circular/linear, but seriously, if the boards wanted to waste a question on that, I was willing to get it wrong. I'm not a machine.
