Ib nucleic acids Study guides, Revision notes & Summaries

Concise study notes from 2022 IB HL Biology. Attained a Level 7 in exam. CORE: Topic 1: Cell Biology Topic 2: Molecular Biology Topic 3: Genetics Topic 4: Ecology Topic 5: Evolution and Biodiversity Topic 6: Human Physiology ADDITIONAL HIGHER LEVEL: Topic 7: Nucleic Acids Topic 8: Metabolism, Cell Respiration and Photosynthesis Topic 9: Plant Biology Topic 10: Genetics and Evolution Topic 11: Animal Physiology

The document describes in detail the role, structure and use of nucleic acids in the body. The document talks about DNA, Adenine, Thymine, Cytosine and Guanine. These are mostly class notes and syllabus notes. I recommend using this document when revising for the test, especially a topic test. There is also info about proteins.

IB Biology - Unit 7 - Nucleic Acids HL 100% Solved Antiparallel strands DNA is anti-parellel, meaning the strands run in opposite directions to each other. If one has a 3' at the top the other has a 3' at the bottom, Purines Adenine and Guanine. Pyrimidines Cytosine, Thymine and Uracil Nucleosomes Used for packing DNA, made up of a length of DNA around a group of 8 histones Supercoiling of DNA Winding of DNA strands, this can reduce the size of DNA by 10000x, using nucleos...
