Question

Biological role of restriction endonuclease

Answer 1

restriction endonucleases act as biological scissors....
these cleave DNA at specific places called palindromic sites....
these are greatly helpful in biotech as vector nd dna can be cleaved by same RE nd later can b joined by ligase to form recombinant molecule...

hope this helps... PLZ MARK BRAINLIEST...

Answer 2

$\huge{ Restriction\: Endonuclease-}$

》Restriction endonuclease are the molecular scissors which cuts the DNA at the enda.

》They have specific recognitipn sites on the DNA strans characterized by some specific base pairs.

》It first suspects the entire strand of the DNA and once it find its recognition site, it binds to the DNA and cuts the two opposite strands.

》These recognition sites are known as palindromic sequence.

》It cuts the DNA strand a little away from the palindromic sequence.

》It cuts the opposite strands between the same two base pairs which results in the formation of overhanging stretches called Sticky Ends.
