Geneticengineering

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

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…

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*)

Keywords genetic engineering genetically modified organisms insulin beta-carotene herbicide

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.

A gene on a human chromosome is identified, for example, the gene for insulin.

Examples of genetic engineering

Read the information on page 38 and 39 to identify the advantages and disadvantages of using genetic engineering for these three examples.

Production of human insulin

Beta-carotene in wild rice

Herbicide-resistant crops

Used to be extracted from pigs but now it is extracted GM bacteria it can be used by vegans.

Decreases the number of animals killed.

Can be made in large quantities and cheaply.

Doesn’t suit every diabetic.

Needed by humans to make vitamin A.

Contaminate other crops by crossbreeding.

Might harm people.

Reduce the amount of crop spraying.

May produce herbicide resistant weeds.

Loss of biodiversity.

Write a piece of for a campaign website, arguing if you are either for or against genetic engineering.
