Verified step by step guidance

Identify the components involved in the problem: nucleotides are the building blocks of nucleic acids, which include DNA and RNA.

Understand the structural formation of nucleic acids: DNA is known for its double-stranded structure, while RNA typically exists as a single strand.

Recognize the specific structure formed by DNA: DNA strands wind around each other to form a double helix, a key feature of its molecular architecture.

Differentiate between the options given: RNA Single Strand refers to RNA's typical structure, Protein Alpha Helix is a secondary structure in proteins, and Lipid Bilayer is a structural component of cell membranes.

Conclude that the structure formed when two strands of nucleotides wind around each other is the DNA Double Helix, based on the characteristics of DNA.
