BIOSC 0150 Edition 1nd Lecture 2 Outline of Last Lecture I Lipids and Cell Membranes Outline of Current Lecture II DNA III DNA to RNA A The process from DNA to RNA is transcription IV Nucleotides V Gel electrophoresis Current Lecture Biomolecules Nucleic acids to proteins Lipids and proteins make the membrane semi permeable and DNA codes for these proteins Hemoglobin protein transports oxygen and DNA codes for the hemoglobin in Red Blood precursors cell Every cell except red blood cells are codded for DNA Not all cells have the same DNA antibodies change DNA slightly Transcription the process from DNA to RNA occurring in the nucleus Proteins are made of amino acids Small difference in DNA can change an organism Two nucleic acids in the DNA double helix store information Two nucleic acids run anti parallel in a DNA double helix Crystallography x ray process used to determine DNA structure Nucleotides are linked to form nucleic acids Activated Monomers driving factors for polymerization reactions These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute Nucleotide monomers made of sugar phosphate and nitrogenous base groups Ribose the sugar in nucleic acid Nucleic acids have a sugar phosphate backbone and polarity DNA base pairing involves hydrogen bonding Base pairing allows for DNA to RNA transcription The sizes of DNA pieces can be determined using gel electrophoresis
