Learning Objectives

Describe genetic modification as changing the genetic material of an organism by removing, changing or inserting individual genes

Outline examples of genetic modification:

the insertion of human genes into bacteria to produce human proteins

the insertion of genes into crop plants to confer resistance to herbicides

the insertion of genes into crop plants to confer resistance to insect pests

the insertion of genes into crop plants to improve nutritional qualities

Over 100 million children in the world are deficient in vitamin A. This deficiency often leads to blindness. A gene for beta-carotene, a precursor of vitamin A, can be inserted into plants to alleviate this widespread deficiency.

Golden Rice

A few genetically modified (GM) crops, e.g. maize and soya bean, are being grown on a large scale in the USA.

Genetically Modified Organism (GMO)

Many other projects are still at the experimental stage, undergoing trials, and awaiting approval by regulatory bodies.

Other examples of genetic modification

The human insulin gene is inserted into bacteria, which then secrete human insulin.

Production of human insulin

The bacterium, Bacillus thuringiensis, produces a toxin that kills caterpillars and other insect larvae. The toxin has been in use for some years as an insecticide.
