14. Which of the following is used as a vehicle to introduce new genes into organisms? A. DNA ligase B. PCR Q. Restriction enzymes p. Vectors

The correct answer is p. Vectors.<br /><br />Vectors are used as vehicles to introduce new genes into organisms. They are typically plasmids or viruses that can carry foreign DNA into a host cell. DNA ligase, PCR, and restriction enzymes are all tools used in genetic engineering, but they do not serve as vehicles for introducing new genes into organisms.
