watson and crick published a paper regarding their discovery of dna structure. as part of the paper's conclusion, they stated that based on their model of the double helix, it would be relatively easy to figure out how dna replicates. which statement best describes a characteristic of dna that would support this idea? hydrogen bonds between the nitrogen bases can be broken easily to allow new strands to be made. covalent bonds between the nitrogen bases can be broken easily to allow new strands to be made. hydrogen bonds between the sugar and phosphate molecules can be broken easily to allow new strands to be made. covalent bonds between the sugar and phosphate molecules can be broken easily to allow new strands to be made.
