A Twitter Office Hour

I did not expect this, but today I had a Twitter Office Hour!

@kmkubo What is solution density? :)
— Fatima (@fmr37) March 13, 2014

@fmr37 Solution density is amount per volume, such as 3 mg per mL (3 mg/mL). Also can refer to student brains after reading my answer keys.

@kmkubo LOL too funny!!!! I'm pray in and hoping your final won't be the end of me.

Another question:

@kmkubo would a decrease radius of rotor decrease RCF? :)
— Fatima (@fmr37) March 13, 2014

@fmr37 Yes, lower R means lower RCF http://t.co/HdSN9qfrdI check out the formula - woohoo!

“@kmkubo: @fmr37 Yes, lower R means lower RCF http://t.co/IMlxkSaG1p check out the formula - woohoo!” THANK YOU!

And still more questions:

@kmkubo Would you use #microfiltration for #hemoglobin? #biotech
— Fatima (@fmr37) March 13, 2014

@fmr37 #hemoglobin is really small, so you would need #ultrafiltration. #microfiltration is for #microbes (much larger than #molecules).

@kmkubo Would a #chelator in a #DNA solution most likely bind to #Mg2+? #biotech
— Fatima (@fmr37) March 13, 2014

@fmr37 that's right - a #chelator, such as EDTA, would bind to #Mg+ to calm down those evil nucleases! >:(

Nevertheless, test anxiety still remains...

@kmkubo is about to kill us with his final! Lol :'( #biotech
— Fatima (@fmr37) March 14, 2014

@kmkubo and I just died. Haha #biotech #myprofessoraintplayin #finals
— Fatima (@fmr37) March 14, 2014

But a teacher can always be hopeful...
