Understanding protein synthesis and the effects of treating a cell with RNAase.

You start with a normal functioning cell where all parts of protein production are working properly. You treat a cell with RNAase that prevents production of mRNA. For each of the following molecules, describe if their concentrations will increase above 100 molecules, decrease below 100 or remain the same and why. molecule -------Starting number mRNA-----------100 molecules tRNA-------------100 molecules Amino Acids----100 molecules Protiens----------100 molecules
