-8 The DNA molecule has the shape of a double helix. The radius of each helix is about 10 angstroms (1 Å = 10¯ cm). Each helix rises about 34 Å during each complete turn, and there are about 2.9 x 108 complete turns. Estimate the length (in Å) of each helix. (Round your decimal part to two decimal places.) 9.87 X x 10¹0 Å
