Oswald avery used different types of enzymes in his experiments to denature molecules including proteins and dna. this way, he could determine which one was the "transforming principle". what was he able to conclude

This is more formally called the Avery-MacLeod-McCarty experiment. This experiment was done to demonstrate that bacterial transformation is caused by DNA. In Griffith's experiment, a rough strain of S. pneumoniae which is non-virulent which did not kill the mouse. A smooth strain of S. pneumoniae which is virulent killed the mouse. A heat-killed smooth strain of S. pneumoniae which was assumed to be non-virulent did not kill the mouse. However, the combination of a rough strain and a heat-killed smooth strain killed the mouse. This proves that the DNA from the heat-killed smooth strain lead to bacterial transformation of the rough strain into the smooth strain, therefore killing the mouse.

Neostigmine. Mechanism of Action: Inhibits the hydrolysis of acetylcholine by competing with acetylcholine for attachment to acetylcholinesterase at sites of cholinergic transmission. It enhances cholinergic action by facilitating the transmission of impulses across neuromuscular junctions.
