1 Molecular Genetics DNA = Deoxyribonucleic Acid

2 Chromosomes are tightly coiled and compacted DNA DNA is twisted and wrapped around organizing proteins called histones, which are super coiled into chromosomes

3 A T C G G C 5' 3' deoxyribose phosphate nucleic acid Rules A always pairs with T C always pairs with G hydrogen bond covalent bond DNA Structure (schematic diagram) Adenine Guanine Cytosine Thymine
