DNA - The double helix
Link: http://www.nobelprize.org/educational/medicine/dna_double_helix/dnahelix.html
DNA - The Double Helix is a online simulation which demonstrates the component and structure of a DNA molecule. The mini games included allow students to build double helix strands and at the same time learn about the history of DNA discoveries and other concepts of genetic materials. The games are time-limited and quite challenging which will keep the students focused and engaged. This simulation is ideal as a class revision activity where students can reflect on their knowledge of DNA and the nucleotide bases.

Syllabus Outcomes:
NSW Science K–10 (incorporating Science and Technology K–6) Syllabus
Outcomes:
- SC5-14LW analyses interactions between components and processes within biological systems
- SC5-15LW explains how biological understanding has advanced through scientific discoveries, technological developments and the needs of society
- SC5-7WS processes, analyses and evaluates data from first-hand investigations and secondary sources to develop evidence-based arguments and conclusions
- LW3 Advances in scientific understanding often rely on developments in technology, and technological advances are often linked to scientific discoveries.
b. identify that during reproduction the transmission of heritable characteristics from one generation to the next involves DNA and genes
c. identify that genetic information is transferred as genes in the DNA of chromosomes
d. outline how the Watson-Crick model of DNA explains:
– the exact replication of DNA
– changes in genes (mutation)
NSW Biology Stage 6 Syllabus
Students:
- 9.3.3.2.1 identify that DNA is a double-stranded molecule twisted into a helix with each strand comprised of a sugar-phosphate backbone and attached bases – adenine (A), thymine (T), cytosine (C) and guanine (G) – connected to a complementary strand by pairing the bases, A-T and G-C
- 14.1 analyse information to:
a) identify trends, patterns and relationships as well as contradictions in data and information
