BIOL 101 1st Edition Lecture 5 Outline of Last Lecture I Lipids continued II Protein Structure a Amino Acids b How are proteins made from amino acids c A protein shape determines its function Lets use this table to highlight the four different levels of protein structure and briefly characterize each Outline of Current Lecture I Nucleic Acid II The Cell a What exists in what type of cell Current Lecture I Nucleic Acid A DNA deoxyribonucleic acid a Monomers ATCG nucleotides B RNA ribonucleic acid a Monomers AUCG nucleotides C Draw a nucleotide include the phosphate group sugar and nitrogenous base Phosphate Sugar base H or OH D What type of bond allows DNA to form a double helix Hydrogen bond weak bond that can be easily broken We will talk more about DNA in Unit II of the course Lactose tolerance is caused by a mutation in the DNA that keeps the lactase gene on we make a lot of lactase RNA which allows us to make a lot of lactase protein II Cells 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 Cell component Cell wall We can target the synthesis of the macromolecules that make up the cell wall killing the bacteria and not us Penicillin inhibits cell wall synthesis in bacteria and is one of the most widely used antibiotics to date Smooth ER synthesis of lipids processing of harmful substances and calcium storage Rough ER synthesis and packaging of secretory proteins G Prokaryote Plant Animal ol yes Plant cells are no gi surrounded by a rigid yet highly dynamic cell wall Plasma membrane yes yes yes Nucleus no Yes Yes DNA yes Yes Yes RNA yes Yes Yes Nucleolus no Yes Yes Ribosome yes Yes Yes Endoplasmic Reticulum no Yes Yes Golgi Body no Yes Yes Lysosome no No plants have organelles with the same function but are not yet identified as lysosomes Yes Mitochondrion no Yes Yes Photosynthetic pigments yes Yes No Chloroplast no Yes No Central Vacuole no Yes No Flagellum yes yes Yes Complex cytoskeleton no yes yes Body SORTS AND SHIPS modifies the proteins once they leave the ER and ships them to other place Lysosomes breaks stuff down its like a recycling center like damaged organelles digestive properties
