The DNA molecule comes in the form of a double helix, meaning two helices that wrap around
Question:
The DNA molecule comes in the form of a double helix, meaning two helices that wrap around one another. Suppose a single one of the helices has a radius of 10Å (1 angstrom Å = 10−8 cm) and one full turn of the helix has a height of 34Å.
