1To produce animals with certain desirable characteristics by selective breeding, humans take advantage of
- Athe natural variations that exist among individuals
- Bthe ideal traits produced by genetic engineering.
- Crecombinant plasmids with foreign DNA>
- Ddrugs and radiation that can cause new mutations to arise.
2What has been an advantage of producing transgenic plants?
- Aincreasing the food supply
- Busing more pesticides
- Cproducing clones
- Dstudying human genes
3A plant cell is successfully transformed if
- Aa plasmid enters the cell and the cell breaks down the plasmid
- Bthe cell integrates foreign DNA into one of its chromosomes.
- Cthe cell reproduces normal offspring, which also produce offspring.
- Da plasmid is unable to enter the cell.
4Which of the following findings, if true, would support CRITICS of GM crops?
- ABt corn is proven harmless to butterflies.
- BBt cotton requires farmers to use less insecticide on their fields.
- CBt corn reduces the populations of bees needed to pollinate the plants.
- DBt cotton produces high crop yields than other cotton.
5What is an advantage of using transgenic bacteria to produce human proteins?
- AThe human proteins produced by transgenic bacteria work better than those produced by humans.
- BTransgenic bacteria can produce human proteins in large amounts.
- CThe human proteins produced by transgenic bacteria last longer than those produced by humans.
- DTransgenic bacteria can produce human proteins used to make plastics.
6The process of making changes in the DNA code of a living organism is called
- Aselective breeding.
- Bgenetic engineering.
- Cinbreeding.
- Dhybridization.
7One reason farmers often choose GM crops over non-GM crops because GM crops are
- Aless controversial
- Bless expensive
- Cmuch productive
- Dmuch safer
8A DNA molecule produced by combining DNA from different sources is known as
- Aa mutant.
- Ba hybrid.
- Ca polyploid.
- Drecombinant DNA.
9Gene therapy is successful if the
- Aviruses carrying the replacement gene infect the person’s cells
- Breplacement gene is REPLICATED in the person’s cells.
- Creplacement gene is EXPRESSED in the person’s cells.
- Dreplacement gene is successfully spliced to viral DNA
10Certain drugs can be used in plant breeding to make polyploid plants. These drugs
- Achange the number of chromosomes found in cells.
- Bchange eukaryotic plants into prokaryotic plants.
- Cfrequently cause mutations, which create new alleles and genes.
- Dinsert foreign DNA into plant chromosomes.
11What kind of technique do scientists use to make transgenic organisms?
- Ahybridization
- Binbreeding
- Cinducing of mutations
- Dgenetic engineering
12Which statement below might be used by someone who is arguing against the use of GM crops?
- AGM crops reduce the amount of land and energy that need to be devoted to agriculture because they have high yields.
- BGM crops need more insecticide to be used than other crops because they grow faster.
- CThe patents for the seeds of GM crops are held by big companies, which may raise prices and force small farmers out of business.
- DNo studies have shown that GM crops are dangerous to human health.
