FOCUS QUESTION

How does DNA determine an organism’s traits?

The map breaks this topic into its core concepts, connected by labeled relationships. Each link is written so it can be read as a complete statement — not just an unlabeled line between boxes.

Concepts and relationships

  • DNA made of Nucleotides.
  • DNA forms a Double Helix.
  • Nucleotides join as Base Pairs.
  • DNA contains Genes.
  • DNA packaged into Chromosomes.
  • Genes code for Proteins.
  • Proteins determine Traits.

How to read this map

Begin with DNA’s structure, follow how genes code for proteins, and see how proteins determine traits.

Learning objectives

  • Describe the structure of DNA.
  • Explain what a gene is.
  • Connect genes to proteins and traits.
  • Relate DNA to chromosomes.
Review standard: Terms and relationships were checked against standard secondary-school biology descriptions. Sources: OpenStax Biology 2e — DNA and Genes.
