Genetic Engineering

By Rhianna Taylor

What is Genetic Engineering?

• Genetic engineering can also be called genetic GM or modification.

• It is different to cloning, even though some steps involved in cloning are the same as the ones in genetic engineering.

The differences

Cloning• It produces exact copies• Genes get copied within the

same species

GM• It produces a unique set of

genes• The genes can be swapped

across species.

Genetic Modification of an

Organism

Choose an organism with a gene that you want copied and put

into another organism.

A gene is cut out using enzymes and then placed into another organisms Chromosome. The chromosome now has the

‘good’ gene and is placed into

another organism.

Genetic Engineering to produce a Chemical

Useful gene to make the

chemical, e.g. insulin

Gene is cut out using enzymes and inserted into a plasmid.

The plasmid is placed into a bacteria and left to

reproduce.

The bacteria reproduces and it

now has the chemical insulin.
