Genetics 3000 Kate Tsai Chapter 11: DNA Organization Key Terms  Primary Structure- nucleotide sequence (A-T, G-C)  Secondary Structure- double stranded helix  Tertiary Structure- higher order packing  Super coiling- either adding more spins (over rotating) or unraveling DNA and taking away spins (under rotation)  Positive Supercoil- add rotations  Negative Supercoil- remove rotations  Chromatin- complex of DNA and proteins in eukaryotic chromosomes, contain histones  Scaffolding Proteins- non-histone, play a role in folding and packing  Nuclease- cuts DNA, resulting in multiple fragments identical in size
