Document Summary
Nucleic acids: polymers of nucleotides, phosphodiester bond, sugar-phosphate backbone, nucleosides, nucleotides, nitrogenous bases, pentose sugar, phosphate group, deoxyribose, ribose, purine, pyrimidine, nucleotide functions. Rna primary sequence/structure, reading nucleic acid sequences, base complementarity, dntps, Dna secondary structure, major groove, minor groove, antiparallel double helix, higher order. Dna structure differences between rna and dna, rna secondary structure, types of rna. Hereditary information passed on after generations in eggs and sperm. Information stored in genes, which determine characteristics of species and individuals. Building blocks for cell structures, catalyze chemical reactions, regulate gene activity, cell communication. Sequence of subunits in dna polymer directs rna synthesis. Structure and chemical properties make it ideally suited to carry genetic information. Packing: compact chromosomes duplicated and appointed for daughter cells; dna accessed by proteins that replicate and repair dna ribo nucleic acid (rna) Rna directs ordering of aas in a peptide chain.
