Statement A : All endonucleases cut RNA at specific sites Statement B : Endonucleases are found in viruses
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
A palindromic sequence in DNA is one in which the 5' to 3' base pair sequence is identical on both strands. Restriction enzymes recognize and cut within specific palindromic sequences, known as restriction sites, in the DNA and produce DNA strands with the sticky ends. It cuts both the strands of DNA at the palindrome site. This is usually a 4- or 6 base pair sequence. Both statements are incorrect.
