What method allows researchers to reduce the expression of a target gene, even in wild type organisms that have not previously been genetically modified?

a. gene knockout
b. tilling
c. rnai
d. saturation mutagenesis

c. RNAi

Explanation:

RNA interference is technology which uses RNA for increasing or decreasing the expression of the target gene. RNA molecules will act as neutralizing agent by targeting the expression of mRNA and destroys it by preventing its expression in to protein.

. ... RNAi  technology is very precise, efficient and much better in its stability than the antisense technology.  

this protocol provides a detailed procedure for agarose-based ip to purify and enrich the protein of interest.
