Final answer:
The sequence of nucleotides in DNA determines the production of proteins, with nucleotides being the building blocks of nucleic acids.
Step-by-step explanation:
The sequence of nucleotides in a DNA molecule determines the protein that will be produced. Nucleotides are linked together in a particular sequence, which is unique to an individual's or species' DNA or RNA. These sequences dictate the amino acid sequence of every protein in a cell, which is then produced through the process of transcription of DNA to RNA followed by translation of RNA into proteins. Nucleotides, the building blocks of nucleic acids, consist of a phosphate group, a sugar, and a nitrogen-containing base. There are four different kinds of nucleotides in DNA, distinguished by their nitrogenous bases: adenine (A), cytosine (C), guanine (G), and thymine (T).
