Question

Which of the following statements is true of Restriction enzymes originate from ____. Question 20 options: A) They are programmed to cut the DNA at specific interval lengths (i.e. every 1000 bp). B) They cut DNA at sequences that read the same forwards as backwards. C) Each kind of restriction enzyme recognizes a different restriction sequence. D) They usually cut the DNA at the same spot on both strands. E) Two of the above are correct. F) Three of the above are correct. G) All the above are correct. Save

Explanation / Answer

Three of the options are correct because the restriction enzymes are found in bacteria.Bacteria uses restriction enzymes to kill viruses. So they usually cut DNA at the same spot on both strands and each kind kind of restriction enzyme recognizes a different restriction sequence and also they are programmed to cut the DNA at specific interval lengths. So i gues options A,C,D are correct and am not sure about that they cut DNA at sequences that read same forwards and backwards.
