Final answer:
True. DNA can form primary, secondary, and tertiary structures.
Step-by-step explanation:
True. DNA can form primary, secondary, and tertiary structures. The primary structure of DNA refers to the linear sequence of nucleotide bases. The secondary structure forms when the DNA molecule twists into a double helix shape. Finally, the tertiary structure is the three-dimensional folding of the DNA molecule. These structures are essential for the proper functioning of DNA.
