Which of the following statements about the structure of DNA molecules is true?
There are three hydrogen bonds between AT pairs.
The nucleotides are arranged in a linear, unbranched pattern.
The sugar-phosphate backbone runs the same way on each DNA strand.
A, B, and Z-form DNA are all right handed helixes.
