BMS 300 1st Edition Lecture 9 Outline of Last Lecture I Phospholipid orientation in water micelle liposome planar bilayer II Lipid mosaic model of biological membrane transmembrane proteins III Proteins as amino acid polymers amino acid structure 1 amine 2 carboxylic acid 3 R group peptide bond formation IV Protein primary structure amino acid sequence V Protein secondary structure hydrogen bonding alpha helix beta sheet 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 Outline of Current Lecture I RNA and its transcription from DNA RNA types 1 mRNA 2 tRNA 3 rRNA 4 regulatory RNA structure 1 5 carbon sugars ribose 2 phosphodiester bonds 3 bases purines adenine guanine pyrimidines cytosine uracil II RNA polymerase and transcription initiation III Promoter where you start TATA box IV Transcription factor DNA binding protein to promoter recruitment of RNA polymerase V Transcription of RNA from DNA read DNA 3 to 5 generate RNA 5 to 3 VI RNA editing cut out introns leave extrons edit RNA in nucleus VII RNA to cytoplasm leave exons translation RNA s working together Current Lecture RNA structure the structure is important because the 3 can link to the 5 carbon etc you can link the two structures and they form a phosphodiester bond in the middle you can then repeat this pattern over and over just like DNA all of the 1 can have one of four bases attached adenine guanine cytosol and uracil all of the 2 carbons will be a hydroxyl because of the ribose the uracil and the thymine are related structures thymine is found in DNA and uracil is found in RNA which allows for more flexibility in the structure the only difference is uracil has an H and thymine has a H3C adenine pairs with thymine in DNA and pairs with uracil in RNA because of the hydroxyl at the bottom of this structure we are not required to make another strand for the RNA to bind to RNA is a single stranded molecule
