  - nitrogenous bases, sugar, and phosphates   
  -  sugar and phosphates
  - a polymer of nitrogenous bases

Answers

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 pentosesugar, 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.
