Study Guide 4 Nucleic Acids (Kopachik) Terms to know Adenine Antiparallel: 5’→3’ on one but 3’→5’ on other Base: substance that reduces the hydrogen ion concentration of a solution Complementarity: G-C, A-T Cytosine Deoxyribose: the sugar in DNA DNA (deoxyribonucleic acid): the genetic material that organisms inherit from their parents, sugar = deoxyribose, nitrogenous bases = C,G,A,T usually double-stranded *function: stores hereditary information DNA replication: the process by which a DNA molecule is copied Guanine Messenger RNA (mRNA): encoding information for amino acid sequence of proteins Nucleoside: portion of a nucleotide without any phosphate group Nucleotide: each polynucleotide consists of monomers Phosphodiester bond: Polarity: 5’PO 4 to 3’OH Polynucleotide: nucleic acids are macromolecules that exist as polymer Pyrimidine: one six-membered ring of carbon and nitrogen atom (C,T,U) Ribose: sugar in RNA Ribosomal RNA (rRNA): three types making up part of the ribosome in which translation occurs RNA (ribonucleic acid): one strand of DNA is the template, sugar = ribose, nitrogenous bases = C,G,A,U usually single-stranded *function: carrying instructions from DNA to ribosomes Thymine Transcription: making RNA from DNA template Transfer RNA (tRNA): adaptor molecule between mRNA and amino acids Translation:making polypeptide from mRNA template Uracil Main points: 1. Nucleic acids are polymers of nucleotides.
