Gel Electrophoresis 1. This technique is used to sort pieces of DNA by:

2. What other type of molecules can be sorted using this method?

3. What is used to move the DNA pieces through the gel?

4. Which pieces move the fastest & furthest?

5. What supplies do you need to make the gel?

6. What is agarose made from?

7. What is a buffer and why is it added?

8. How long does the gel take to solidify, and what happens as it cools?

9. What are the 2 reasons that you add buffer to the DNA sample to be tested?

10. Why do you use a DNA size standard?

11. What is your proof that the current is flowing through your buffer

12. What do we use to stain DNA?

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
