how changing one nucleotide within a DNA molecule of a cell could change the structure of a protein produced by that cell. What effect would this change have on the protein's function?

Step 1
DNA is composed of sequences of four nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). A change in one of these nucleotides is called a point mutation. Show more…
