Genetic engineering can be done by transferring a desirable gene from a donor organism into the genome of a recipient organism.

It is useful in agriculture and technology and has helped further scientific research.

Genetic engineering can be carried out on plants and animals.

Some of the most interesting tests by scientists are below:

Rows of bananas

Banana vaccines

Hate injections? Scientists have discovered a way of turning the humble banana into a life saving vaccine. An engineered part of a virus is injected into the fruit where it multiplies thousands of times. When eaten, it produces antibodies which fight off deadly disease.

Usually the recipient organism is a bacterial cell because:

  • Bacterial DNA is easily manipulated.
  • Bacteria can reproduce very rapidly.

The bacteria then have the ability to make whatever the desirable gene codes for, like insulin for example.
