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...
