M-TURNER Q/A Proteins 1. At the pH (ab 7.0) what happens to the amino group on an aming acid? →It acts as a base and gains a proton, giving it a positive charge 2. L-Amino acids can be distinguished from D-amino acias By their Water Solubility → By the position of -COOH, -NH₂ and R-groups around thei'r a Carbon 3. A peptide bond is... →Joins a Carbonyl Carbon and an amino nitrogen atom →Irwolves a condensation reaction →15 Covalent 4. What type of bonds/forces Stabilize protein Secondary Structure → Hydrogen Bonds 5. What type of bond (forces Stabilize tertiary Structure →lonic bonds →Hydrogen bonds → Hydrophobic forces 6. What happens when a protein denatures Loses Secondary and tertiary Structure. Nucleic Acids 11. Whats the difference btwn a nucleotide and nucleoside →Nucleotides contain one or more phosphate groups whereas nucleosides DO NOT Contain phosphate groups 2. If the sequence of a DNA Strand is 5'-TGAC-3' what's the sequence of the opposite strand →Find the CB pairs and inverse it! TGAC Answer is 5'GTCAB' ACTE 刀 3. The nucleic acid Chain grows by which functional group of two nucleotides? 5' phosphate and 3' hydroxyl group 4. Which Statement is true → Monomers used to grow a nucleic acid are nucleoside triphosphates (NTPS) 5. The DNA double helix is held together by what? →2 antiparalled DNA Strands held together by hydrogen bonds between A-T and C-G 6. How are the Structures of DNA and RNA Similar for both molecules? →Their Sugar prosphate backbones are formed by Phosphodiester linkages between the phosphate group
