Which of the following statements regarding the structure of DNA is false?

a. The DNA molecule has a uniform diameter.





b. In a DNA molecule, adenine bonds to thymine and guanine to cytosine.





c. Watson and Crick received a Nobel Prize for their description of the structure of DNA.





d. The sequence of nucleotides along the length of a DNA strand is restricted by the base-pairing rules.





e. The DNA molecule is in the form of a double helix.Which of the following statements regarding the structure of DNA is false?
d. The sequence of nucleotides along the length of a DNA strand is restricted by the base-pairing rules.


dA-dT and dG-dC base pairs can occur in any order within DNA molecules

A -- is true


dA-dT and dG-dC base pairs are the same length, and occupy the same space within a DNA double helix. Therefore the DNA molecule has a uniform diameter.

B -- is true





C -- is true

E -- is trueWhich of the following statements regarding the structure of DNA is false?
i know B, D, and E are right so its between A or C but im thinking A is false.
