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.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.
