A recombinant Ti plasmid can be used to
A) insert genes from any source into a bacterium.
B) insert bacterial genes into a human.
C) insert genes from any source into a plant.
D) remove specific genes from a plant.

Question

Quizplus · Accepted Answer

A recombinant Ti plasmid is used as a vector to introduce foreign genes into plant cells. Hence, choice C is the correct option. The Ti plasmid is used as a delivery system that can transfer genes encoding desirable traits (such as insect resistance, herbicide tolerance, etc.) into the plant cell genome. The plasmid is naturally found in Agrobacterium tumefaciens, which causes crown gall disease in plants. However, researchers have modified the Ti plasmid to make it a useful tool for genetic engineering.
