Document Summary
Each nucleotide has one phosphate group associated with it: the specific nature of the carb associated w/ nucleotide pentose sugar, position 1 in carb is nitrous oxide. Guanine and adenine are double ringed structures: how they are involved lends themselves to symmetry, purine based. Ribose and deoxyribose: rna single stranded. Capacity to be more reactive than double stranded molecule. Ribonucleotides, which contain the sugar ribose and form rna. Deoxyribonucleotides, which contain the sugar deoxyribose and form dna. The linear distance is equal: this is antilinear, guanine can only form h bonds w/ cytosine. The polymerzation of nucleic acids is endergonic: polymerization of nucleic acids is an endergonic process catalyzed by enzymes, energy for polymerization comes from the phosphorylation of the nucleotides. Phosphorylation is the transfer of one or more phosphate groups to a substrate molecule. This raises the potential energy of the substrate and enables endergonic reactions. Take phosphate group"s energy and stick it to another molecule.
