True about Restriction enzyme: (A) Palindromic, (B) Produce DNA sticky end, (C) Restict replication of DNA, (D) Restriction sites are not specific
Answer is A. Restriction enzyme or restriction endonuclease is an enzyme that cuts DNA at or near specific recognition nucleotide sequences known as restriction sites.Recognising a palindromic sequence enables them to cut both strands of DNA at the "same" site because the strand will have the same sequence only in different directions at that site.
