What is the DNA backbone made of?
A. a nitrogenous base and a sugar molecule
B. nitrogenous bases, sugar, and phosphates
C. sugar and phosphates
D. a polymer of nitrogenous bases
Answer (3)
the answer is C.sugar and phosphates. yw hope that helped :)
DNA or deoxyribose nucleic acid is a genetic material, which transmits information from the parent cell to the offspring . It is present in the nucleus or found in the nucleoid .
The correct option is:
Option C . sugar and phosphates
DNA is made up of:
Nitrogenous bases such as adenine, cytosine , thymine, and guanine are involved in the specific pairing that provides the helical structure of DNA .
The DNA consists of a pentose sugar , known as deoxyribose .
The backbone of the DNA is made up of the phosphate group attached with sugar , which provides DNA with a negative charge .
Thus, the DNA backbone is made up of phosphate and pentose sugar .
Therefore, Option C is correct.

The DNA backbone is composed of a repeating sugar (deoxyribose) and phosphate groups, making the correct answer option C. This backbone supports the nitrogenous bases that form the core of the double helix structure of DNA. It is essential for maintaining the overall structure and function of DNA in genetics.
