Genetic Methods
Experimental analysis of proteins typically require expression and purification of proteins. Expression is achieved by manipulating DNA that encodes the protein(s) of interest. Hence protein analysis usually requires DNA methods, especially cloning. Other examples include
- conceptual translation- many proteins are never directly sequenced, but their sequence of amino acids is known by "conceptual translation" of a known mRNA sequence. See genetic code.
- site-directed mutagenesis allows new variants of proteins to be produced and tested for how structural changes alter protein function.
- insertion of protein tags such as the His-tag. See also green fluorescent protein.
- Proteins that are involved in human diseases can be identified by matching alleles to disease and other phenotypes using methods such as calculation of LOD scores.

Famous quotes containing the words genetic and/or methods:
“What strikes many twin researchers now is not how much identical twins are alike, but rather how different they are, given the same genetic makeup....Multiples don’t walk around in lockstep, talking in unison, thinking identical thoughts. The bond for normal twins, whether they are identical or fraternal, is based on how they, as individuals who are keenly aware of the differences between them, learn to relate to one another.”
—Pamela Patrick Novotny (20th century)
“We can best help you to prevent war not by repeating your words and following your methods but by finding new words and creating new methods.”
—Virginia Woolf (1882–1941)
