Question

which of the following characteristics of the structure of dna allows it to carry a large amount of hereditary information?
○ the sequence of bases
○ phosphate-sugar backbones
○ complementary pairing of bases
○ different five-carbon sugars

Explanation:

To determine which DNA structure characteristic carries hereditary info:

• "Phosphate - sugar backbones" provide structural support, not info storage.
• "Complementary pairing of bases" is for replication/transcription, not info encoding.
• "Different five - carbon sugars" is incorrect (DNA has deoxyribose, RNA has ribose; DNA’s sugar is consistent).
• "The sequence of bases" (A, T, C, G) acts like a code, with different sequences encoding different genetic info.

Answer:

the sequence of bases
