BIOSC 0150 1nd Edition Lecture 2 Outline of Last Lecture I. Lipids and Cell MembranesOutline of Current Lecture II. DNAIII. DNA to RNAA. The process from DNA to RNA is transcription IV. NucleotidesV. Gel electrophoresisCurrent LectureBiomolecules: 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 slightlyTranscription- 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 helixCrystallography- x-ray process used to determine DNA structure-Nucleotides are linked to form nucleic acidsActivated Monomers- driving factors for polymerization reactionsThese 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 groupsRibose- 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
