Solution
Q: Which of the following is not an example of protease activity?
Answer: A) some protease cleave the phosphodiester bond between nucleic acid residues
Explanation: The enzyme involved in such reaction is called a phosphodiestrase enzyme (it breaks down the phosphodiester bond present between nucleic acid residues). A Phosphodiester enzyme is different from a protease enzyme that breaks down protein sequences into smaller peptides and eventually into amino acids.
