The correct answer is: At end of the polynucleotide chain.
Restriction enzymes belong to a larger class of enzymes called nucleases. They are of two types: exonucleases and endonucleases. Exonucleases remove nucleotides from the ends of the DNA whereas, endonucleases make cuts at specific positions within the DNA.
