The base pairs in a DNA strand are held together with hydrogen bonds. In what way would a cell be most affected if these were covalent bonds instead?

A: The cell would need to make new DNA each time the strand was opened.

B: The cell would only be able to open and close the DNA strand when it replicated.

C: The cell would have to take in and use more energy in order to break the covalent bonds.

D: The cell would need to replace the nitrogenous bases each time the DNA strand opened.
