 **Uppgift**
 
-A gene of interest was amplified and verified using the blue/white screening method. The
-plasmids from two bacterial colonies, one blue colony and one white colony, were purified. Then
-restriction enzyme digestion was performed, and the samples were run on a gel as follows: white
-uncut, white cut, blue uncut, blue cut (see figure below). After imaging the gel, we can conclude
-that while there is plasmid DNA in all samples, the white sample was probably mixed with the
-blue sample. Explain what finding in the gel indicates the white sample was probably mixed with
-the blue sample by referring to the size/number of bands. Account for the other source of error
-for this outcome besides pipette tip contamination from sample to sample. (4p) (Max 200 words)

 **Answer**
 
-the findings in the gel that indicate that the samples were mixed are the lines in
-the white uncut sample. It has two visible bands, with one lining up quite nicely
-with the blue uncut bands in size. If the plasmid is uncut, than there shouldn't
-be two distinct bands because the sample only consists of an uncut product. The
-white uncut should also have a larger amount of base pairs than the blue
-uncut because we have transformed a gene of interest into it, but they seem to
-have the same amount.  
-a source of error for this outcome could be that the colony picked for the white
-cut may have been close to a blue colony - causing a small amount of the blue
-colony to be accidentaly picked.
