Visual: Genetic Engineering Process

Painted 4-stage genetic engineering sequence for recombinant insulin: (1) human insulin gene cut from DNA with restriction enzymes, (2) bacterial plasmid cut at same site, (3) human gene inserted into plasmid and sealed with ligase, (4) recombinant bacteria divide and produce insulin.

Remember: Cut gene (restriction enzyme) → Insert into vector/plasmid (ligase) → Transform bacteria → Bacteria multiply → Harvest product

Quick Recall Flashcards

What is genetic engineering?

The direct modification of an organism's genome by inserting a gene from another organism (or a modified gene) to give it a new or altered characteristic. The resulting organism is called a genetically modified (GM) organism.

How is insulin produced using genetic engineering?

The human insulin gene is inserted into bacterial plasmids. The bacteria are grown in large fermenters and produce human insulin protein. This insulin is then purified for use by diabetics. Before this, pig or cow insulin (slightly different) was used.
