Restriction enzymes & DNA ligase (article) | Khan Academy
How can pieces of DNA from different sources (such as a human gene and a bacterial plasmid) be joined together to make a single DNA molecule? One common method is based on restriction …
Bacterial transformation & selection (article) | Khan Academy
Because of these possibilities, it's important to collect plasmid DNA from each colony and check to see if it matches the plasmid we were trying to build. Restriction digests, PCR, and DNA sequencing are …
