Make a concept map (see BioSkills 12) that relates DNA's primary structure to its secondary structure. Your diagram should include deoxyribonucleotides, base-stacking interactions, purines, pyrimidines, phosphodiester linkages, DNA's primary structure, DNA's secondary structure, complementary base pairing, and antiparallel double helix.

Verified step by step guidance

1. Identify and define the key components: Start by defining each component involved in the structure of DNA. Deoxyribonucleotides are the building blocks of DNA, consisting of a phosphate group, a sugar (deoxyribose), and a nitrogenous base. Purines (adenine and guanine) and pyrimidines (cytosine and thymine) are types of nitrogenous bases. Phosphodiester linkages refer to the bonds between the phosphate group of one nucleotide and the sugar of another.
2. Describe DNA's primary structure: DNA's primary structure is the linear sequence of deoxyribonucleotides linked by phosphodiester bonds. This sequence encodes genetic information and is specific for each organism.
3. Explain base-stacking and complementary base pairing: Base-stacking interactions are hydrophobic interactions between adjacent bases that stabilize the DNA structure. Complementary base pairing is the specific hydrogen bonding between purines and pyrimidines (A pairs with T, and G pairs with C) which helps in forming the double helix structure.
4. Link to DNA's secondary structure: DNA's secondary structure refers to the three-dimensional double helix formed by two antiparallel strands of nucleotides held together by complementary base pairing. The antiparallel nature means that one strand runs in the 5' to 3' direction and the other in the 3' to 5' direction.
5. Create the concept map: Begin with 'Deoxyribonucleotides' at the top, connecting downwards to 'DNA's primary structure' through 'Phosphodiester linkages'. Branch out from 'DNA's primary structure' to 'Base-stacking interactions' and 'Complementary base pairing'. These then lead to 'DNA's secondary structure', which is further described by 'Antiparallel double helix'. Include 'Purines' and 'Pyrimidines' branching off from 'Deoxyribonucleotides' to indicate their role in base pairing.
