In a DNA strand, the nucleotides are linked together by 3'-5' phosphodiester linkage (bonds ) to form a dinucleotide. More nucleotides can be joined in such a manner to from a polynucleotide chain.

Explanation:
Nucleotides are the building blocks of DNA. DNA stands for Deoxyribonucleic acid. A nucleotide is made up of three components:
1. A nitrogenous base
2. A 5-carbon sugar called deoxyribose
3. A phosphate group
The nitrogenous base can be of four types:
1. Adenine (A)
2. Thymine (T)
3. Guanine (G)
4. Cytosine (C)
The nitrogenous base, deoxyribose sugar, and phosphate group make up a nucleotide. These nucleotides are then joined together to form a DNA strand. The nucleotides are linked together by phosphodiester bonds.
Phosphodiester Bond:
A phosphodiester bond is a chemical bond that joins the phosphate group of one nucleotide to the hydroxyl group on the sugar of another nucleotide. These bonds are formed through a condensation reaction, where a molecule of water is released.
The bond is formed between the 5' carbon of one nucleotide's sugar ring and the 3' carbon of the sugar ring of the next nucleotide. The bond is formed between the phosphate group attached to the 5' carbon and the hydroxyl group attached to the 3' carbon. This linkage between the nucleotides forms the sugar-phosphate backbone of the DNA strand.
Conclusion:
Therefore, option B, i.e., phosphodiester bonds, is the correct answer as they are the chemical bonds that join the nucleotides together to form a DNA strand.
