A) Cuts DNA molecule at random
B) Cuts DNA from specific palindromic site
C) Restrict DNA synthesis
D) Synthesize DNA
Correct Answer: B
Solution :
Each restriction endonuclease functions by 'inspecting' the length of a DNA sequence. Once it finds its specific recognition sequence, it will bind to the DNA and cut each of the two strands of the double helix at specific points in their -sugar-phosphate backbones. Each restriction endonuclease recognizes a specific palindromic nucleotide sequences in the DNA.
