A) The enzyme cuts DNA molecule at identified within the DNA.
B) The enzyme binds DNA at specific sites and cuts only one of the two strands.
C) Which enzyme cuts the sugar-phosphate backbone at sites on each strand.
D) The enzyme recognizes a specific palindromic nucleotide sequence in the DNA.
Correct Answer: B
Solution :
Restriction enzymes cut DNA molecules at a particular point by recognising a specific sequence. Each restriction endonuclease functions by inspecting the length of a DNA sequence. Once it finds its specific points in their sequence, it will bind to the DNA and cut each of the two strands of the double helix at specific points in their sugarphosphate backbone.
