Which of the following is true about restriction endonucleases?
A) They make a blunt cut on the two DNA strands so that there are no single-strand regions.
B) They make staggered cuts on the DNA so that single-strand ends are formed that can be used to insert foreign DNA cut with the same enzyme.
C) Some make a blunt cut on the two DNA strands so that there are no single-strand regions and some make staggered cuts on the DNA so that single-strand ends are formed that can be used to insert foreign DNA cut with the same enzyme.
D) Depending on the incubation conditions,the same enzyme can either make a blunt cut on the two DNA strands so that there are no single-strand regions OR make staggered cuts on the DNA so that single-strand ends are formed that can be used to insert foreign DNA cut with the same enzyme.
