Problem 9. Bending DNA into a loop. The Young's modulus for DNA is 300 MPa and its cross-sectional radius is 1 nm. DNA of length 50 nm is formed into a circular loop. A. What is the radius of curvature of this loop? Express your answer in nm. B. How much energy is required to form the circular loop? Express your answer in scientific notation in units of Joules. C. What is this bending energy in units of KBT. Recall that 1 KBT = 4.14 x 10-21 J (at T = 300 K)
