Genetic Engineering Flashcards
1
Q
Genetically modified crops have had their genes modified to make what?
A
TO MAKE THEM RESISTANT TO VIRUSES, INSECTS OR HERBICIDES
2
Q
Why have sheep been genetically engineered?
A
TO PRODUCE SUBSTANCES, LIKE DRUGS, IN THEIR MILK THAT CAN BE USED TO TREAT HUMAN DISEASE
3
Q
What is gene therapy?
A
GENETIC DISORDERS SUCH AS CYSTIC FIBROSIS ARE CAUSED BY FAULY GENES. SCIENTISTS ARE TRYING TO TREAT THESE DISORDERS BY INSERTING WORKING GENES INTO SUFFERERS
4
Q
What happens in genetic engineering?
A
A USEFUL GENE IS CUT FROM ONE ORGANISMS CHROMOSOME USING ENZYME
ENZYMES ARE THEN USED TO CUT ANOTHER ORGANISMS CHROMOSOME AND THEN INSERT THE NEW GENE
