Breaks the DNA sample into smaller pieces (hence, “fragment”), and then the pieces can be separated by size on a gel. Restriction enzymes are known to cut strands of DNA at specific regions and can be added to a DNA sample which has been subjected to the Polymerase Chain Reaction. http://www.scq.ubc.ca/wp-content/endonuclease2.gif Wheeler and Waikel R estriction F ragment L ength P olymorphism (RFLP)

The patterns of the bands that result from restriction digests in exons 6 and 7 will determine blood type. The digests will produce fragments of different sizes; the presence of these different bands will determine your blood type!

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
