Question

q 3. nucleotides are composed of a phosphate group, a sugar, and a nitrogenous base. dna is made up of long strands of nucleotides. which part of the above molecule can differ between nucleotides? there is no differing structure in nucleotides the nitrogenous base the phosphate group the sugar clear all

Explanation:

Nucleotides are composed of a phosphate group, a sugar, and a nitrogenous base. In DNA, the phosphate group and sugar (deoxyribose) are consistent across nucleotides. However, the nitrogenous base can vary (e.g., adenine, thymine, cytosine, guanine). These different bases are what distinguish one nucleotide from another in terms of their molecular structure.

Answer:

the nitrogenous base
