In the extraction of DNA from a Banana, alcohol is added to the filtrate after filtration. What will happen if you do not filter the solution inside the zip lock prior to addition of cold alcohol?

On the graph that relates absorbance to flavin concentration, draw a horizontal line that starts at the point on the y-axis that corresponds to the absorbance of your unknown sample and ends at the curve you drew through your data points . Next draw a vertical line that starts at the point where the horizontal line intersected the curve and ends at the x-axis. The point where this vertical line intersects the x-axis corresponds to the concentration of flavin in your unknown sample. What was the letter on the tube with your unknown sample? What is the concentration of the flavin in your unknown

SDS is required to unfold proteins during SDS-PAGE electrophoresis and it is included in both the loading and running buffer. If SDS is not included in the running buffer.... the proteins in your sample may partially renature thus affecting migration. the gel will not conduct current in the absence of SDS. there is no effect on the samples. the proteins in your sample will be graded.

You intend to drop a potato stick in each cup. a. What data will you collect for each potato stick? b.  In how many of the solutions will the potato sticks remain unchanged? c.

What is the experimental procedure illustrated in the figure above?  What label (1-3 words) would you write next to each of the 5 arrows in the procedure? )  Briefly write a concise but complete description of the figure closely following the labels you have used in your answer to the second part of the question.

Briefly describe how you would make 500 mls of a 1X electrophoresis running buffer from a 15X stock solution.
