What kind of binding connects one phosphoric acid across a DNA strand to another phosphoric acid on the complimentary DNA strand?
A) Hydrogen binding
B) Amino acid binding
C) Deoxyribose binding
D) None of the above; phosphoric acids do not link across the two DNA strands.
Hydrogen Binding
Hydrogen bonding is a type of weak chemical bond that is usually intermolecular, occurring when a hydrogen atom covalently bound to a highly electronegative atom such as N, O, or F experiences attraction to another electronegative atom.
Phosphoric Acid
A weak acid with the chemical formula H3PO4, used in food flavoring, beverages, dental products, and as an industrial etchant.

Final Answer :
D
Explanation :
Phosphoric acids in DNA are part of the sugar-phosphate backbone of each strand and do not link across to the complementary strand. The connection between the two strands is made through hydrogen bonds between the nitrogenous bases, not through any direct linkage of phosphoric acids.
