⁠@@dripler4033are isolation of DNA fragments leakha hai !! DNA ko bina cut kere DNA k fragments kese alag kerenge maine apni PYQ ki book m check kiya hai D hi sahi hai

[@Ytlectures1234]

​Isme gel electrophoresis ki ​baat nhi ho rhi Yaha para isolation matlab hai ki bacterial cell ya plant / fungi cell ko different enzymes ( cellulase/lysozyme/chitinase , RNAse , protease) se treat karake dna isolate karna phir us dna ko RE se cut karna 1) isolate 2) Cut by RE and obtaining gene of interest from isolated dna 3) amplification 4) insertion@@siddharthjain1078

[@shikshamaratha7116]

​@@dripler4033 I think isme B,C,D,A hi hoga because isolation of DNA nahi isolation of dna fragments bola hai toh fragments toh tabhi banenge jab dna ko cut karenge . I am not sure but i think option d sahi hoga .

2:52:05 ma'am with due respect I want to let you know that I think the correct option according to your neet 2020 phase 1 question no. 91 is option d. But according to your option arrangement in this particular question the answer should be option a. Bcoz in ncert it is written that "each restriction ENDONUCLEASE functions by inspecting the length of a dna sequence." And here the option a) is restriction ENZYME ... So according to that sense I think the wrong option I mean the answer is option a. Btw ma'am huge love and respect ❤ Chapter clear ho rha hai ❤
