Students should be able to describe genetic engineering as a process which involves modifying the genome of an organism by introducing a gene from another organism to give a desired characteristic |
|
What is genetic engineering? |
|
|
|
An example of genetic engineering is plant crops have been genetically engineered to be resistant to diseases or to produce bigger better fruits. |
|
What examples are there of genetic engineering in plant crops? |
|
|
|
Bacterial cells have been genetically engineered to produce useful
substances such as human insulin to treat diabetes. There are links
with this content to role of biotechnology. (biology only).
|
|
(Biology only) What examples in medicine uses genetically engineered bacteria? |
|
|
|
Students should be able to explain the potential benefits and risks of genetic engineering in agriculture and in medicine and that some people have objections |
|
What are the potential benefits and risks of genetic engineering in agriculture and medicine? |
|
|
|
In genetic engineering, genes from the chromosomes of humans and other organisms can be ?cut out? and transferred to cells of other organisms. |
|
What occurs within the chromosomes during genetic engineering? Brainstorm what the terms genetic engineering, genetic modification and gene therapy mean.
List examples of genetic engineering. |
|
|
|
Crops that have had their genes modified in this way are called genetically modified (GM) crops. |
|
What do we call crops that have genes from other organisms in them? |
|
|
|
GM crops include ones that are resistant to insect attack or to herbicides. |
|
How does genetic modification increase the longevity of crops? |
|
|
|
GM crops generally show increased yields. |
|
How does genetic modification increase the yield of a crop? |
|
|
|
Concerns about GM crops include the effect on populations of wild flowers and insects. Some people feel the effects of eating GM crops on human health have not been fully explored. |
|
What concerns are there about GM crops? Research advantages and disadvantages of GM crops. What characteristics may be modified? Produce a web page or a table of benefits versus concerns. |
|
|
|
Modern medical research is exploring the possibility of genetic modification to overcome some inherited disorders |
|
How is genetic modification important in medicine? |
|
|
|
(HT only) Students should be able to describe the main steps in the
process of genetic engineering.
|
|
|
|
|
|
(HT only) In genetic engineering:
- enzymes are used to isolate the required gene; this gene is inserted into a vector, usually a bacterial plasmid or a virus
- the vector is used to insert the gene into the required cells
- genes are transferred to the cells of animals, plants or
microorganisms at an early stage in their development so that they
develop with desired characteristics. Interpret information about genetic engineering techniques and to make informed judgements about issues concerning cloning and genetic engineering, including OM crops. |
|
(HT only) What are the steps involved in genetic engineering? Use a model to describe genetic engineering techniques.
EW : How is human insulin is produced by bacteria and what advantages are there of using this over porcine insulin. |
