Why is genetic modification more advantageous than traditional breeding methods?
It lead to higher yields
It involves the transfer of genes within same species
The desired changes can be achieved in one generation
The techniques involved are very simple and not costly

Bacteria
Viruses
Fungi
Protozoa

Oestrogen
Thyroxine
Insulin
Dopamine

Which of the following statements is not true regarding the clone population of a certain plant species?
clones produce flowers and fruit faster than their parent plants
The number of chromosomes of the clones is the same as the parent plants
The cones produced brought about variation to the species of the plant
The clones produced have the same characteristics as the parent plant
What is the application of genetic engineering techniques to replace defective genes in humans?
Gene alteration
gene modification
Gene replacement
Gene therapy
Genetically modified plants such as rice are created using
traditional breeding methods
Recombinant DNA technology
Special minerals in the soil
Plant cell as precursor
Which of the following modifications can be made in tomatoes using recombinant DNA technology?
more nutrients can be added
The shelf life of tomatoes can be extended
The taste of tomatoes can be made sweeter
Which stage in the production of insulin by genetic engineering is represent in Diagram 2?
Human gene is inserted into plasmid
Human gene is inserted into a bacterium
Plasmid is inserted into a human chromosomes
Bacterial gene is inserted into a human chromosome
What are the advantages of GMO and GMF Production?
The GM potatoes have higher annual yields than conventional potatoes
The content of GM milk is modified to give a more desirable flavor
Release of GMOs into the environment can disturb ecological balance
Threats to human health

Anemia
Haemophilia
Thalassemia
Down Syndrome
