Assume that a viral DNA molecule is a 11-μm-long strand with a uniform 20-Å diameter. Assuming complete flexibility of the molecule, will it fit inside a viral head that is a 8×10−2-μm-diameter sphere? Part A)What is the volume of the viral head in cubic angstrom (Å3)? Hint: Recall that the volume of a sphere can be calculated using this formula: Volume= (4/3) x pi x r2, where r stands for radius of the sphere. Also note that 1Å=0.1 nm. Express...
