Four wells were each injected with fragments that were prepared from DNA samples using identical techniques. This laboratory procedure is known as 1. cloning 2. gel electrophoresis 3. chromatography 4. use of a dichotomous key

Its gel electrophoresis. It helps to separate DNA fragments

Gel electrophoresis

[ssheffield897271]

gel electrophoresis is when you take 4 different wells that are contained in a previously prepared gel. when you inject the DNA into these 4 identical wells, you can determine patterns and things that arise within the gel, depending on what you are looking for-it will tell you, and this is what it is most commonly used for, which DNA can be linked with another. paternity tests and crime tests can be determined with this procedure.

i know for a fact it's gel electrophoresis.
