GM Arabidopsis produces dsRNA to:
a) To produce more protein product:
- This option is incorrect. GM Arabidopsis does not produce dsRNA to increase protein production. Protein production in plants is regulated by various mechanisms, such as gene expression, transcription, translation, and post-translational modifications. dsRNA does not directly influence these processes.
b) To stop transcription:
- This option is incorrect. dsRNA does not stop transcription. In fact, dsRNA can trigger a biological process called RNA interference (RNAi), which regulates gene expression at the post-transcriptional level.
c) Knock out specific parasitic genes in the nematode:
- This option is correct. GM Arabidopsis can produce dsRNA to knock out specific parasitic genes in nematodes. This is achieved through a phenomenon known as RNAi. When dsRNA is introduced into a cell, it can be processed into small interfering RNAs (siRNAs) by an enzyme called Dicer. These siRNAs can then bind to complementary sequences of target mRNA molecules, leading to their degradation and subsequent inhibition of protein production. By designing dsRNA specifically targeting genes essential for nematode survival, the GM Arabidopsis can produce dsRNA to knock out these genes, thereby providing resistance against nematode parasitism.
d) To make DNA non-functional:
- This option is incorrect. dsRNA does not make DNA non-functional. dsRNA primarily affects gene expression at the post-transcriptional level through RNAi, as mentioned earlier.
In conclusion, the correct answer is option 'c'. GM Arabidopsis produces dsRNA to knock out specific parasitic genes in nematodes through RNA interference (RNAi).
