points dna inside living cells becomes charged as each base pair steals a pair of electrons from surrounding water molecules and releases a pair of hydrogen ions (a) do some research and determine the typical number of base pairs in a human chromosome (not the number in the y your answer should includea reference to the source or sources used in your answer. (3 points) (b) estimate the electric force between two typical chromosomes assuming that they are held one micrometer apart in vacuum. assume that the two chromosomes are coiled up and can be treated as point charges, each with a charge of 2 extra electrons per base pair. (5 points) (c) in a living cell dna is surrounded by water that contains both negatively and positively charged ions that are free to move (since water is a conductor). how do you think these ions will respond to the presence of a charged chromosome? (2 points)

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaĻv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and Ļ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and Ļ = 1.2 kg/m3.
