Answer:
Sugars and phosphates
Explanation:
DNA is deoxyribonucleic acid.
The backbone is based on a repeated pattern of a sugar group (deoxyribose) and a phosphate group.
The image below shows one straightened-out strand of DNA with a backbone of alternating sugars and phosphates.
A is wrong. There is no ribose in DNA.
B is wrong. The nucleic acids A, C, G, and T join one strand of DNA to the other.
C is wrong. There is no RNA in DNA.
I believe that the right answer is Heat energy
I’m not sure about your experiment can you explain?
