BACE Test Questions and Answers Graded A+ what represents the correct order of assembly in the cell Amino acid, polypeptide, protein t/f: A single base pair change in a gene's DNA sequence can affect the shape and function of the protein it encodes. true t/f:The three-dimensional structure of a protein is largely determined by the amino acid sequence. true A structural gene's code is 5' TAC ATG CCC TTA ATC 3', what will the mRNA transcript be? 3' AUG UAC GGG AAU UAG 5' Circular, long DNA containing several thousand genes Prokaryotic DNA Cytoplasmic, circular DNA containing only a few genes plasmid DNA Linear, long pieces of DNA with many thousands of genes, contained within a nucleus Eukaryotic DNA How does DNA differ from one species to another? The number of genes and non-coding regions The enzyme maltase catalyzes the break down of maltose into glucose. A technician added maltase to a solution of maltose to be incubated at 37°C. Samples were taken from the reaction tube every five minutes over the course of one hour, to measure the glucose concentration. After an hour, the technician noticed the water bath failed to reach 37°C (it only warmed to 25°C). Which of the following is the most likely outcome of the reaction? The enzyme activity would decrease, yielding the same level of glucose over a longer time period. Carbon dioxide as a by-product benefits the brewing and baking industry in a process called fermentation. When microorganisms (usually yeast) undergo fermentation, they obtain their energy by: Anaerobic respiration t/f:A solvent is the dissolved matter in a solution. false Carbohydrates Example: cellulose. Functions: energy storage, receptors, structure of plant cell wall. Lipids Example: cholesterol. Functions: membrane structure, energy storage. Nucleic acids example: RNA. Functions: information storage and transfers Proteins example: enzyme. Function: structure, receptors and transport Which of the following should be used to calculate the amount of compound required to make a solution? Molecular weight bond type?: NaCl Ionic bond type?: H2O polar covalent bond type?:CH4 nonpolar covalent What is a disadvantage to using prokaryotes in the production
