Rules of pairingnucleotide adenine pairs with nucleotide Thymine via 2 hydrogen bonds. A=T nucleotide cytosine pairs with guanine via 3 hydrogen bonds G ≡ C 1 A =T & G ≡C pairs are called

complementary base pairs2 Each single DNA strand is a polymer made

of deoxynucleotide monomers3 Deoxyribonucleotide monomers are

linked from phosphate to deoxyribose sugar in the DNA backbone

4 Weak Hydrogen bonds join complementary base pairs of the 2 strands of the double helix to form the rungs of the DNA ladder

5 The strands are anti-parallel so that one strand has its phosphate group at the top & hydroxyl on the bottom of the strand, while the other is oriented oppositely.

Cells have 4 types of macromolecules (also known as polymers)Polymer monomer main funcitonsCarbohydrates monosaccharides or sugars store energy

form structuresLipids like fats fatty acids store energy or phospholipids build cell membranes or steroids hormones, communication

Nucleic acids DNA deoxyribonucleotides store genetic information RNA ribonucleotide allow protein synthesis

Proteins amino acids workers (tools) of the cellenzymes, regulators, structural components
