Answer:

a. to treat a disease characterized by a gene that is not expressed.

Explanation:

The RNA interference (RNAi) technique is widely used in molecular biology to inhibit target gene expression at the post-transcriptional level. The RNAi technology uses small interfering RNAs (siRNAs) consisting of 18-22 nucleotides that bind to complementary acid nucleics (i.e., DNA and RNA), thereby inhibiting target gene expression. Recently, it has interestingly been discovered that small RNA sequences targeting promoter regions can also be used to activate the expression of endogenous target genes through a mechanism called RNA activation (RNAa).

Vika [28.1K]
Cover crops suppress weeds and reduce damage by diseases, insects and nematodes. Many cover crops effectively suppress weeds as: a smother crop that outcompetes weeds for water and nutrients. Residue or growing leaf canopy that blocks light, alters the frequency of light waves and changes soil surface temperature.
