Question

use the question below to see how well you understand the methods by which geneticists transform plants.
which of the following does not introduce new genes into a plant to transform it?
choose the best answer
a microparticle injection
b rna interference
c agrobacterium tumefaciens infection
d all of the above introduce new genes into the plant.

Explanation:

Microparticle injection and Agrobacterium tumefaciens infection are methods that directly introduce new, exogenous genes into plant cells to achieve genetic transformation. RNA interference (RNAi) works by silencing existing plant genes using small RNA molecules, without adding any new genetic material to the plant.

Answer:

b. RNA interference
