Video narration
Agar kisi paudhe ka koi gene band karna ho, to kya use gene hatana padega? Isse phone ke instruction message se samajhiye. DNA ki soochna mRNA naam ke copied message mein aati hai. Yahi message protein banane ka nirdesh bhejta hai. Ab mod: gene hatana nahi padta. Usi sequence se matching double-stranded RNA, yani dsRNA, mRNA ko pehchan kar nasht kar deta hai. Message gaya, protein nahi bana. Gene wahin rehta hai, lekin uska expression band ho jata hai - isi ko RNA interference, yani gene silencing kehte hain. NCERT mein paudhe ko aisa RNA banane ki kshamata di jati hai, jo root-knot nematode Meloidogyne incognita ke zaroori genes ke mRNA se match karta hai. Unke proteins nahi bante, isliye nematode infection rukta hai aur paudha bach jata hai. To uttar hai: matching dsRNA, target mRNA wala phone message hata deta hai, gene nahi. mRNA hatte hi protein production ruk jati hai.
