It is synthesized by free-floating ribosomes of cytoplasm in humans:
Correct answer: D. DNA helicase
- A. Pancreatic lipase
- B. Salivary amylase
- C. Insulin
- D. DNA helicase
Explanation
DNA helicase, since it is the only one whose final destination is inside the cell. These Helicases come under the class of enzymes that are essential to all organisms. These are motor proteins that move directionally along with the nucleic acid, separating two hybridized nucleic acid strands, using the energy from ATP hydrolysis. Their role or function is to unpack an organism's genetic material.
