Summary
| Description |
English: Seen here is a diagram of agarose gel for DNA Profiling: RFLP (restriction fragment length polymorphism) Analysis. To the left is a picture of a DNA fingerprinting experiment, and the diagram on the right is the line drawing of the picture to show the distributions of DNA fragments. By comparing the ditributions, people can determine which suspect is guilty. The reason that DNA fragments move to different distances is they have different lengths and sizes: shorter/smaller fragments would move faster and further. Under an electric field, nucleic acid molecules move negatively charged molecules through agarose gel, and identical fragments would move the same distance.
1. Known DNA 2. DNA of suspect 1 3. DNA of suspect 2 4. DNA from the crime scene A. DNA fragments: larger fragments B. Wells: where people load DNA samples C. DNA fragments: smaller fragments that are further separated D. Agarose gel: electric field |
