By far the best way is to write them down first, and then start playing with each set of equations, one at a time - and spend time solving problems (possibly even more difficult ones than on the MCAT, like those available from Khan Academy courses or MIT OCW). There are generally two parts to wieldi...

I have been instructed, under penalty of whippings, to not promise an exact date for the release of the shortened exams. I can however say that we started moving on this immediately after the AAMC announced this change and that they will be provided on the shortest timeline possible while ensuring a...

This one pops back up every now and then, but I enjoy this logic puzzle every time: The table gives the odds of experiencing poverty within the specified years (see the paragraph above it). But since we live in sequence and age in order from 0 to death, an older person must have lived through all th...

In order to accelerate the sled up the ramp you will need to overcome the force of static friction and the component of the force of gravity acting parallel to the ramp. So we just go ahead and find what those are: Framp = mgsin(30) = 100*0.5 = 50 N Fstatic = mgcos(30)*mu = 100*0.87*0.5 = 43.5 N Fop...

To start off, even though this doesn't answer your bolded question: D is the correct answer because competition between test and control DNA is what produces an accurate signal that represents copy numbers for each chromosome. So it is not a flaw in the method, rather it is the method. Your reasonin...

1 dalton is simply 1 amu.

I'm not sure where you got mol/L from, molarity doesn't factor into answer this. Simply realize that log(6) = 1000000, therefore the exclusion limit is 1 million Daltons or 1000 kiloDaltons.

Notice that the lysing described occurs in the presence of extremely strong acids, in strongly non-physiological conditions. In physiological oxidizing conditions, disulfide bridges are formed between cysteine residues. The processes shown in the diagrams (following the statement in paragraph 1) sho...

I know that humans have 46 total chromosomes and that 44 are autosomes/somatic and 2 are germ cells. You may need to un-know this. (Jokes aside, this is a very common area of confusion) Let's clean our understanding of this up a bit: All human cells have 23 pairs of homologous chromosomes*. 22 of t...

I apologize for being late to continuing this discussion. I've tried to post twice and lost the message both times so far. The key idea at work is that RT-PCR couldn't possibly be performed without an RNA template. If we used the coding strand that we're given, it would just be regular PCR, and we w...

You are totally correct, this is a typo and should say "superior colliculus". Good catch!
