BMS 300 1st edition Lecture 5 Outline of Last Lecture I Protein structure role of R groups in tertiary structure of a protein 1 folding of hydrophobic and hydrophilic R groups 2 role of geometric shape 3D in proteins function liquid substitute role of R groups in transmembrane protein 1 orientation of hydrophobic R groups in lipid bilayer 2 single pass across the membrane 3 multiple pass as R channels II Structure of eukaryotic cells prokaryotes 1 bacteria 2 archaea eukaryotes 1 specialization of function through membrane and compartments chromosomes in the nucleus 1 DNA molecules histones as organizing and regulating DNA binding proteins 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 histones as species ribosomes and endoplasmic reticulum Outline of Current Lecture I The nucleus DNA chromosomes histones nuclear pores II Ribosomes protein synthesis composed mostly of RNA III Endoplasmic Reticulum rough endoplasmic reticulum short endoplasmic reticulum IV Vesicles transport containers V Golgi apparatus protein modification 1 proteins from RER VI Vesicle plasma membrane 1 exocytosis lysosomes Current Lecture Nucleus nuclear pores open pores in the nucleus there are several hundred proteins that regulate traffic into and out of the nucleus descriptive highly structured organization the chromosomes are always confined in the nucleus the biology revolves around the central dogma regulates the movement of RNA Central dogma DNA stores information about protein structures transcribes DNA into RNA that is confined to the nucleus RNA contains the information for the amino acid structures cytoplasmic of protein protein is the translated from RNA RNA is made from DNA only in the nucleus Ribosomes the factory to make proteins mostly RNA key player in proteins synthesis they are responsible for making synthesis of cytoplasmic proteins cytoplasmic structure Endoplasmic
