Recombinant Protein Production in Medicine
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Recombinant DNA technology lets bacterial or animal hosts mass-produce a human protein, such as insulin, by expressing a cloned human gene.
Show
A bacterial host carrying the cloned human insulin gene produces human insulin directly, where earlier treatment relied on insulin purified from pig and cow pancreases.
Watch for
Recombinant insulin is human insulin produced in a bacterial host, not an artificial or animal-derived substitute.
