Extraction of Plasmid DNA, Restriction Digest, and DNA Gel
... Biochemists study protein structure, function and activity. To study protein X, we need it in pure form rather than as a mixture of many proteins. It is not always easy to purify a protein from its natural source. For example, to purify bovine protein X (from cow), you might start by grinding up a p ...
