3. Genetically modified organisms from bacteria to sheep are a very important development of biotechnology which are useful in a number of ways. Which of the following chemicals is NOT made by genetically modified organisms?
hepatitis B vaccine
human insulin
alpha-1-antitrypsin
acetylsalicylic acid
hepatitis B vaccine

- which is the active ingredient in aspirin. Hepatitis B vaccine is made by genetically modified yeast, human insulin by genetically modified bacteria and alpha-1-antitrypsin is found in the milk of genetically modified sheep.
4. In one form of stem cell research the DNA from the cells of a patient is introduced into an empty ovum which is then induced to begin early embryonic development. Stem cells are harvested from this embryo to produce new healthy tissue for the original DNA donor. This is known as:
therapeutic stem cell cloning
embryonic stem cell therapy
adult stem cell therapy
genetic engineering
therapeutic stem cell cloning
Embryonic stem cell therapy involves taking stem cells from excess early embryos from infertility treatment, adult stem cell therapy involves taking stem cells from the adult who needs treatment and genetic engineering involves manipulating and changing the DNA of different organisms to supply the required genes.

5. Gene therapy has been tried in a number of different diseases, although as yet it has not been completely successful in any of them. In one of the diseases listed, the planned approach to gene therapy will work by switching off damaged genes rather than by replacing them with healthy genes. Which of the following diseases is it?
cystic fibrosis
SCID
Huntington’s disease
Duchenne muscular dystrophy
cystic fibrosis
The correct answer is c) Huntington’s disease – in all the other cases the hope is to add the required healthy gene or minigene so that the necessary proteins are made. In Huntington’s disease scientists hope to switch off the gene that causes excess amounts of a particular protein to be synthesised.

6. How long did it take for the Human Genome Project to complete the sequencing of the entire human genome?
10 years
13 years
16 years
19 years

7. Many of the new biotechnological advances are directed at improving and developing medical diagnosis and treatment. There is one that has also played a very important role in advancing crime detection. It is:
gene mapping
genetic modification
DNA fingerprinting
RNA analysis
gene mapping
The correct answer is c) DNA fingerprinting – this looks at the unique patterns in our ‘junk’ DNA and allows the police and forensic scientists to identify criminals – and those who are innocent – by comparing DNA from a crime scene with DNA from a suspect. Gene mapping involves identifying the position of genes on a chromosome, genetic modification means altering the genetic information in a cell or organism and RNA analysis involves sequencing the bases in a piece of RNA
