CHAPTER 16: DNA, RNA, PROTEINS = “Information” molecules CHARGAFF’S RULES: A = T  and  G = C A Purine always bonds to a Pyrimidine REPLICATION (DNA DNA) Site where it starts =  ORIGIN of REPLICATION NUCLEOTIDE SUBUNITS SUGAR = Ribose (RNA)         OR Deoxyribose (DNA) NITROGEN BASES: DNA RNA Adenine Adenine Guanine Guanine Cytosine Cytosine Thymine Uracil RIBONUCLEIC ACID (RNA) Single stranded Sugar = ribose Nitrogenous bases          = A, U, G, (NO T) Can fold up in 3D shape DEOXYRIBONUCLEIC ACID (DNA) • Double stranded • Sugar = deoxyribose • Nitrogenous bases = A, T, G, C (NO U) Strands run in opposite directions (ANTIPARALLEL) Ladder twists into a DOUBLE HELIX Backbone = sugars and phosphates Rungs of ladder = nitrogenous bases Hydrogen bonds between nitrogenous bases hold sides of ladder together
