After the gel was done, Steve inserted the DNA samples with the pipette throught the surface of the buffer...
|
|
|
|
 | |  |
| I was afraid that you might punch the pipet tip through the bottom of the gel, but you did a good job!! | |
 | |  |
|
 |
| | |
| Now i can close the top of the electrophoresis chamber and leave it alone until the bromphenol is about 2/3 the way down the gel. | |
| | |
|

|
After about 45 minutes...
|
|
|
|
| | |
| I cannot wait to find out how is the killer. | |
| | |
|
 |
| | |
| The gel electrophoresis is done and you Steve can remove the casting tray and slide the gel onto UV transiluminator!! | |
| | |
|
|
|
|
the tension is in the air..
|

| Oh,!!I can't believe..We have a killer. The sample that is found on the door knob belong to the butler, who sad that he cut himslef while he was chopping the eggs. | |
| | |
|
|
| | |
| DNA fragment match perfectly with the butler's DNA fragments. | |
