Given below are two statements: Statement I: The outer membrane of mitochondria forms a number of infoldings called cristae towards the matrix to increase the surface area. Statement II: The mitochondrial matrix possesses a single circular DNA molecule, a few RNA molecules, and 70S ribosomes. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Statement I is incorrect because it is the inner membrane of mitochondria, not the outer membrane, that forms a number of infoldings called cristae towards the matrix to increase the surface area for ATP production. Statement II is correct as the mitochondrial matrix contains a single circular DNA molecule, a few RNA molecules, 70S ribosomes, and the components required for the synthesis of proteins. Answer: Statement I is incorrect but Statement II is correct.
