Genetic engineering allows scientists to remove a gene from one organism and insert it into the DNA of another organism. This process can be used for genetic engineering. For example, the gene that makes jellyfish glow in the dark has been used in genetic engineering. The document then provides background information on genetic engineering and examples of how it is used.

1. Genetic engineering
Scientists can remove a gene from one
organism and insert it into a DNA of
another organism.

2. This species of jelly
fish naturally have the
ability to glow in the
dark.
The gene that is
responsible for this
has been used in
genetic engineering…

4. Genetic engineering
WALT: To understand how genetic engineering can be
used to treat diseases and to consider the advantages
and disadvantages behind this technology.
WILF: ~ State what genetic engineering is and list
examples of when it is used. (D)
~ Discuss some of the advantages and disadvantages of
genetic engineering for particular examples. (C)
~ Explain how the process of genetic engineering occurs
using enzymes. (B)
~ Evaluate the issues behind genetic engineering. (A/A*)

5. Use the diagram on 38 to rearrange these statements to
show how the process of genetic engineering takes place.
Bacteria will then reproduce to make lots of copies of the
particular gene.
‘Cutting’ enzymes are used to separate the gene from
the chromosome.
The gene is then inserted into a bacterial plasmid using
‘sticking’ enzymes.
A gene on a human chromosome is identified, for
example, the gene for insulin.

6. A gene on a human
chromosome is identified, for
example, the gene for insulin.
‘Cutting’ enzymes are used to
separate the gene from the
chromosome.
The gene is then inserted into a
bacterial plasmid using
‘sticking’ enzymes.
Bacteria will then reproduce to
make lots of copies of the
particular human gene.
