    2:51:00= in question 4 option D is correct because in this question it ask about restrictions endonuclease .
    and option d tells about dna ligases which is not related to restrictions endonuclease.

    Bhut hi mast lec hai
    Aesa lgra hai jaise movie chal rhi ho har ek cheez sequence me aur iss lec ko dekh ke lag rha hai ki aab aage kya hoga 😂😂mtlb literally bhut mzaa aagya mjhe to ye ch padhke ritu mam se
    Pls aaplog bilkul dekhiye iss lec ko mtlb kisi teacher ne aesa explain nhi kiya maine khud 3-4 teacher se padha but smjh nhii aaya
