All life on earth is based on one of many two-polymer systems, each made up of a protein and a nucleic acid. in a cell, these polymers are, for the most part, charge-balanced, with the nucleic acid in any pair carrying a negative charge and the protein carrying an equal amount of positive charge. consider a distribution of eight of these polymers, where the eight proteins sit together near the center of the cell and the nucleic acids are spread out along the circumference of a circle with the radius equal to one-quarter of the cell diameter, centered on the proteins. part a: - if seven of the eight nucleic acids are at ? /2, 3? /4, ? , 5? /4, 3? /2, 7? /4, and 2? rad, where on the circle must you place the eighth acid to give the system a balanced charge distribution? (hint: begin by making a sketch.)

1) at 3? rad
2) at ? /4 rad
3) at ? /8 rad
4) at ? /3 rad
