A second site, also studied before, is the insulin gene itself, Dr. Todd said.

The insulin gene, once obtained, would be stitched into small circles of DNA called plasmids.

The insulin gene can be inserted in the middle of the ampicillin gene after it has been removed using restriction endonucleases.

The human insulin gene, for instance, is put into bacteria, which then produce the hormone.

Several regulatory sequences in the promoter region of the human insulin gene bind to transcription factors.

DBP binds to an upstream promoter in the insulin gene.

The human insulin gene, for instance, is put into bacteria, which then make insulin for use as a drug.

At the same time he worked with Sinaida Rosenthal, a former student of his father, on cloning the insulin gene from carp.

Scientists can place a human insulin gene inside a bacterium, and that bacterium will produce insulin.

While at Harvard, she was part of the team that discovered the insulin gene.
