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.
