Document Summary
Define nucleic acid, nucleotide, nucleoside, nitrogenous base, pentose sugar (ribose, deoxyribose) and phosphate, including chemistry and bonds. Name 5 common bases and their classification. Have an understanding of nomenclature of nucleosides and nucleotides. Understand the basic chemistry of nucleic acids. Define resonance in bases and its effect on base structure and absorption spectra. Realise that bases can be modified, that there are minor bases in cells and even cyclic ones. Know the functions of nucleic acids and derivatives. Heredity- transfer of characteristics from generation to generation. Information to make a new individual organism is passed on in the reproductive cells (egg and sperm) Genes are part of our genetic material dna- found in nucleus as part of the chromosomes. Major components of nucleus: basic (positively charged compounds) = polymers of amino acids proteins: acidic (negatively charged compounds) 2 types: deoxyribonucleic acid (dna, ribonucleic acid (rna) Not only information storage- making rnas and proteins. Nitrogenous base + pentose monosaccharide + phosphate.
