thnx allot for your input, in summary i doubt its possible distinguish between the three unkown, since only one unkown was used in the gel had we used all three...we should be able to distingish between them

thats beside the point... I just thinking..this be a hole in the system..cause ppl could go too different countries to write their mcat

This ones got me; A buddy of mine said hes gona take the exam in the states, (we are from canada), cause he believes he can score higher there this is based on two ideas americans are less educated than canadians the mcat is curved based on that specific exam lets ignore the first argument of whos smarter (i dont wona start a forum war!) but the second statement got me wondering....what do you guys think?

Hello, I ran a electrophoresis for a intro bio university class. Each group was given two ladder, and two wells, one to use with ECOR1+DNA and one with just the DNA. One group came up with a question that stumbled me; they forgot to put their ECOR1 in their DNA (or just didnt give it enough time to do its magic), but now they have two strands with the same length. The reason I feel the need to help them is because the ladder I filled leaked into their wells, and they ended having three lines show up, two perfectly matching the ladder, and one perfectly matching the uncut. This resulted in them having a rather hard time figuring out how they could get three lines with the furthest one being as far as the uncut. Now for the question, is their anyway to figure out what the unknown is using the uncut? I personally already calcualted the equation to count for bp, but I know that this does not apply to uncoiled, since the equation is based on the ladder, which is linear. The unkown can either be pUC 19, pDrive, or pGen easy, any comment be appreciated!
