The Structure of DNA wall chart is a detailed educational poster that explains the molecular structure, function, and replication of DNA in a clear and visually engaging way. It introduces learners to DNA as the fundamental genetic material found in chromosomes within the nucleus of every cell, setting the foundation for understanding heredity and genetics.

The chart clearly illustrates the DNA double helix, showing the sugar-phosphate backbone, complementary base pairing, and hydrogen bonds. Each nucleotide is labelled, allowing students to see how sugars, phosphates, and bases combine to form the DNA molecule. Base pairing rules are explained in detail, showing how adenine pairs with thymine and guanine pairs with cytosine, reinforcing key examination concepts.

A full section is dedicated to DNA replication, with step-by-step diagrams showing strand separation, base pairing, and the formation of two identical daughter molecules. This makes the process easy to follow and ideal for classroom explanation. The poster also explains chromosomes, genes, and the genetic code, linking DNA structure to protein production and inherited traits.

Historical context is included through a description of the Watson and Crick model, helping learners understand how scientific knowledge developed. This wall chart is ideal for biology classrooms, laboratories, and study spaces, providing a clear visual reference that supports learning, revision, and teaching.
