Question

what type of bonds exist between base pairs? hydrogen ionic covalent oxygen rewatch submit

Explanation:

Base pairs in nucleic acids (like DNA/RNA) are held together by weak, specific bonds that allow the strands to separate for processes like replication and transcription. Hydrogen bonds form between complementary nitrogenous bases: adenine-thymine (or uracil) have 2 hydrogen bonds, and guanine-cytosine have 3. Ionic and covalent bonds are not the primary bonds between base pairs, and oxygen is an element, not a bond type.

Answer:

Hydrogen
