Final answer:

Bases attach to the deoxyribose sugar's 1' carbon, the sugar binds to purines' 9' nitrogen and pyrimidines' 1' nitrogen, while phosphates bind to deoxyribose sugar's 5' carbon, forming the structural framework of DNA.

Step-by-step explanation:

Bases bind to the 1' carbon of deoxyribose sugar. The sugar binds to the 9' nitrogen of purines and the 1' nitrogen of pyrimidines. Phosphates bind to the 5' carbon of deoxyribose sugar.

The structure of deoxyribose sugar in DNA is such that its five carbon atoms are numbered 1' through 5'. The nitrogenous bases, which include both the purines (adenine and guanine) with a double-ring structure and the pyrimidines (cytosine and thymine) with a single-ring structure, bind to the 1' carbon of the deoxyribose sugar. Additionally, the phosphate group is attached to the 5' carbon of the sugar by forming a phosphodiester bond with the 3' carbon of the next deoxyribose sugar, creating the sugar-phosphate backbone of DNA.
