In this video, we explore how RNA interference (RNAi) plays a crucial role in the world of agriculture by controlling roundworms. We find out how a genetically modified plant can induce the RNAi mechanism in roundworms, ultimately killing them.

the bestt video and the most clean and understandable no extra pointgs or enzymes to confuse and the uses of it is explained and how it works is explained perfectly i swear i saw most of videos in yt but tis is so far best acc to me.....

@6:00 how can both the DNA strands undergo transcription ? Only the template DNA strand is supposed to undergo transcription.

@aryankain5481 Жыл бұрын

Yeah but If you read ncert pg 209 in the bottom part saying "The introduction of DNA was such that it produced both sense and anti sense RNA in the host cells"

Because we add modified dna

@aritrasarkar4435 8 ай бұрын

We reverse the promoter and Terminator sites thus transcripting both strands

Why does the double stranded rna form?

@manuthambi8184 6 ай бұрын

It forms because the TWO* RNAs, formed when the cloned gene undergoes transcription, are complimentary to each other. * Only one RNA will be produced in normal transcription. Here, the transcription is producing 2 RNA because of some technicalities when introducing the cloned gene into the host

i had some other doubt , in general , the rna produce is single stranded during replication , why would dna produce double stranded rna in this case ?
