Now, imagine a protein is nearby, which has a +le charge that is 7.0 A away from the DNA backbone, and is situated asymmetrically between two phosphate groups as shown. Below is a sketch of the geometry of the problem, labelling the charges (Qo = protein; Q1. Q: = phosphates) and some relevant distances. 2. Determine the angles 01, 02. 3. In which direction do you expect the positively charged protein to feel a force from to the DNA backbone? Draw a vector in the drawing above, indicating approximately your answer. [Alternatively, make a copy of the circled portion of the drawing and indicate the vector on it. ]7.0 A 3.4 A ; Q1 Q2 1.0 A + 4. Determine the net force on the charge of the protein from this portion (2 phosphates) of the DNA. Your answer should include the magnitude and direction of the force. 5. This question has made some simplifying assumptions in determining the force that acts on the protein. List two assumptions that you expect to have a significant quantitative effect on the answer to question 4. (Some assumptions might not have a large effect; we're interested in which ones you expect may change your answer substantially.) For each assumption, describe how you think the force would change if you did not make this simplifying assumption and instead did your calculation in more detail. [You do not need to do any further calculations! ]
