Which of the following is not the function of plasma membrane?

Options

  1. AEndocytosis
  2. BFormation of intercellular junctions
  3. CSecretion
  4. DDNA synthesis

Correct answer

D. DNA synthesis

Step-by-step solution

The fluid nature of the plasma membrane is important for functions such as cell growth, formation of intercellular junctions, secretion, endocytosis, and cell division. DNA synthesis (replication) occurs in the nucleus, mitochondria, and chloroplasts, but not at the plasma membrane. Therefore, DNA synthesis is not a function of the plasma membrane. Answer: DNA synthesis
