Which experiment would best provide data to support the mechanism by which an ODN inhibits IN activity? Keep IN concentration constant and measure the initial velocity of the reaction at increasing vDNA concentrations in the presence and absence of the ODN. Keep vDNA concentration constant and measure the initial velocity of the reaction at increasing concentrations of IN in the presence and absence of the ODN. Keep ODN and IN concentration constant and measure initial velocity of the reaction at increasing concentrations of vDNA. Keep IN and vDNA concentrations constant and measure initial velocity of the reaction at increasing concentrations the ODN.
