Genetic Engineering – Check Test

1. Genetic engineering is the

A swapping of genes between organisms.

B construction of new genetic codes on DNA.

C hybridising of different species.

D transfer of DNA from one organism to another.

2. The genes of an organism are made up of

A DNA.

B chromosomes.

C plasmids.

D cell nuclei.

3. The normal control of activity in a bacterium

depends on

A foreign genes.

B inserted plasmids.

C chromosomes.

D simple proteins.

4. Plasmids are used to

A cut genes out of chromosomes.

B carry genes into bacterial cells.

C make proteins in animal cells.

D join genes together.

5. The organisms currently most commonly used in

genetic engineering to make useful products are

A plants.

B animals.

C yeasts.

D bacteria.

6. Which line in the table describes the advantages of genetic

engineering over selective breeding.

	Product quantity	Product quality	Product separation
A	small	pure	easy
B	large	contaminated	hard
C	large	pure	easy
D	small	contaminated	hard

7. Selective breeding has disadvantages compared to

genetic engineering because

A the improvements produced are gradual.

B the hybrids only show desired characteristics.

C completely different species can be crossed.

D it is a relatively new development.

8. A disadvantage of current genetic engineering is that

A bacteria cannot make certain complex proteins.

B products may be contaminated by bacteria.

C it is impossible to insert genes into plant cells.

D plasmids cannot be inserted into bacterial cells.
