Question

Restriction endonucleases are enzymes that

• A. Restrict the action of other enzymes
• B. Break phosphodiester bond between specific nucleotides of DNA
• C. Break nucleus into pieces
• D. Break H-bond between two strands of DNA

Answer 1

The correct option is B Break phosphodiester bond between specific nucleotides of DNA

B.Break the phosphodiester bond between specific nucleotides of DNA

Solution : Restriction endonuclease are the enzymes that was originally generated from bacteria and they work by cleaving the sugar phosphate bond of the DNA at specific sites.

So the correct answer is "Break the phosphodiester bond between specific nucleotides of DNA"
