HOW DID THEY MAKE INSULIN FROM RECOMBINANT DNA?
RECOMBINANT DNA IS A TECHNOLOGY scientists
developed that made it possible to insert a human gene
into the genetic material of a common bacterium.
This “recombinant” micro-organism could now produce
the protein encoded by the human gene.
Scientists build the human insulin gene in the laboratory.
Then they remove a loop of bacterial DNA known as a plasmid and …
insert the human insulin gene into the plasmid.
Researchers return the plasmid to the bacteria and …
put the "recombinant" bacteria in large fermentation tanks.
There, the recombinant bacteria use the gene to begin producing human insulin.
Scientists harvest the insulin from the bacteria and …
purify the substance for use as a medicine for people.
