**The preview file is a pdf version of all the slides for you to review before purchasing the real thing
This powerpoint presentation covers Topic 3.4 in the IB Biology curriculum. Specifically, it covers the BASICS of DNA replication (see learning objectives below).
Each slide is labelled with the specific learning objective and animation/video links are provided in the slide notes. The slides are formatted to print well for handouts or revision and I can provide a pdf version upon request.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
**IB Biology Learning Objectives:
3.4.1 – Explain DNA replication in terms of unwinding the double helix and separation of the strands by helicase, followed by formation of the new complementary strands by DNA polymerase.
3.4.2 – Explain the significance of complementary base pairing in the conservation of the base sequence of DNA.
3.4.3 – State that DNA replication is semi-conservative.
