6. These enzymes are called molecular scissors which is essential in making internal cuts in a DNA molecule or vector at specific sites.

• Restriction enzymes

• Restriction proteins

7. What do we call the new molecule after the process of ligation wherein the vector plasmid joined with the gene of interest?

• Gene of interest

• Recombinant DNA

• Recombinant bacterium

8. Bacterial cells as host organisms may express the gene to make _________ products such as insulin and growth hormones

• protein

• lipid

• plant

9. Which of the following describes recombinant DNA technology?

• Mating of organisms with desirable qualities

• Insertion of genes into cells that makes the cells into “factories” to make products

• Enhancing or disrupting the traits of a target organism either mating or molecular technique

10. Which of the following illustrates classical breeding?
