Refer to the paragraph about Kawakubo's group. Kawakubo's group created a glycoprotein with a terminal NAG (i.e., a protein with NAG attached to its end). Their hypothesis is that the terminal NAG, and not the protein component , is responsible for the damage to the cell wall in H. pylori. What would be the most appropriate control for testing this hypothesis?
A) Grow H. pylori in a test tube (in vitro) with no glycoprotein. B) Destroy the H. pylori by exposing them to a hypotonic solution. Then add the glycoprotein and observe. C) Expose other species of bacteria to the glycoprotein. D) Grow H. pylori in a test tube with a glycoprotein that has its terminal NAG removed.
