RNA interference in pest control | Biotechnology and its Applications | Biology | Khan Academy

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.

Oh my ...Deepika Padukone is a closet biotecnology teacher.

[@cokxi]

damnnn, I thought something sounded familar.

[@amitesh0684]

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.....

[@smitapradhan9798]

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

[@aryankain5481]

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"

[@Nunnu-lp7wt]

Because we add modified dna

[@aritrasarkar4435]

We reverse the promoter and Terminator sites thus transcripting both strands

[@user-mr5yt5ls1i]

Yeah I also got same doubt now

[@user-mr5yt5ls1i]

​@@aritrasarkar4435oh is it..ok. thanks 👍

Got it 👍

finally understood... Thanks a ton!

[@Kangsolin_07]

So eazy to understand

[@anjuarasultana3815]

Why does the double stranded rna form?

[@manuthambi8184]

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

[@shivanshithakur8376]

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 ?

Thanks a lot mam, you are a lifesaver

[@BanothRavindrarani]

Thank you mam 🙏

[@himanisharma7085]

Why both strand of r dna forms m rna

[@merik6131]

Yes I too have doubt.if someone can explain

[@akankshamishra12thb77]

​@@hajrashaikh8900 jo gene introduce kiya hai plant mai agar uske dono stand mrna banaye gai , toh wo complementary hoga aur ds rna bn jaaye ga .. toh es se nematode ki activity kaise ruki. Wo toh bna rha apna mrna aur phir us se protein

[@akankshamishra12thb77]

​@@hajrashaikh8900 maine jo padha hai uske according ham nematode ka gene introduce nhi krte balki artificially nematode kai gene ka complementary gene banate aur us complementary gene ko insert krte plant host mai phir yeh complementary gene ek single stranded mrna ko transcribed krta jo ki complementary hoga nematode kai mrna se aur dono bind ho jaate jis se ki nematode ka krna protein nhi bna pata.. agar mai glt hun toh please explain karyeh ..

​@@akankshamishra12thb77wtf how do you guys even get this understanding 💀 retrovirus with RNA genome or mobile genetic element (transposons) can act as a complementary RNA molecule that replicates via an RNA intermediate
