Review the section on “cutting and pasting” on the DNAi web site: >Manipulation >Techniques >cutting and pasting. Watch a gel electrophoresis animation at >Manipulation >Techniques >sorting and sequencing. How does the process of gel electrophoresis separate DNA fragments?This process uses electricity to separate DNA fragments by size as they migrate through a gel matrix.

Gel electrophoresis can be used toseparateDNA fragments WRITING FORMAL LAB REPORTS. You have to understand the material in order to write a good lab report. For this course, I would. like you to seriously regard the lab reports as a means of learning about the subject. If you do not. understand the lab, or how the report should be written, you will be unable to write a good .

Using a pipette, DNA samples are loaded into slots madein the agarose gel. What is the purpose of the agarose gel?Typically, a DNA molecule is digested with restriction enzymes, and theagarose gel electrophoresis is used as a diagnostic tool to visualize the fragments. An electric current is used to move the DNA molecules across an agarose gel, which is a polysaccharide matrix that functions as a sort of sieve.
