• Heamoglobin

Bt maize is toxic to which type of organism

• Insect pest

• The maize itself

• Cows

• Bacteria

What type of molecule is used to cut DNA to insert a gene?

Identify the reason some people are against genetically modifying food crops

• They have an increased yield

• New varieties can be developed

• Pollen produced by the plants could be toxic and harm insects that transfer it between plants.

• They can be made herbicide resistant

Identify a potential benefit of genetically modifying crops

• nsect and pest resistance can be developed and inserted into the plants

• Transfer of the selected gene into other species. What benefits one plant may harm another

• GM crops could be harmful, for example toxins from the crops have been detected in some people’s blood

• GM crops could cause allergic reactions in people

State the term for all the genes possessed by an organism
