AP Biology Multiple Choice Pretest Unit 6 – Gene Activity and Biotechnology Multiple ChoiceChoose the answer that best fits the statement or question.DNA contains the blueprints for building proteins, which perform most of the work of the body’s cells. Which type of protein would amylase be, if it speeds up the digestion of starch?CarrierEnzymeAntibodyHormoneRecognitionThe surface proteins found on individuals with A, B, and AB blood types would be classified as what type of protein?CarrierEnzymeAntibodyHormoneRecognitionWhich of these correctly ranks the organization of proteins from smallest unit to largest molecule?Amino acid → Protein → PolypeptidePolypeptide → Amino Acid → ProteinAmino acid → Polypeptide → ProteinProtein → Polypeptide → Amino acidThe function of a protein ultimately depends on its…ShapePrimary structureAmino acid sequenceAll of the aboveThe shape of a DNA molecule is best represented by which of these illustrations? A B CDWhich part of the nucleotide monomer in DNA is responsible for the “code” that determines how a protein is constructed?The sugarThe phosphate groupsThe nitrogenous basesAll of these are individually read by the enzymes of protein synthesis.A sequence of DNA is analyzed and the number of bases counted. Which of the following statements should be true about this molecule?There should be equal amounts of adenosine and thymine.There should be equal amounts of adenosine and guanine.There should be equal amounts of adenosine and cytosine.There should be equal amounts of adenosine and uracil.Which of these nitrogenous bases are NOT found in molecules of DNA?AdenineCytosineGuanineThymineUracilBefore DNA can be replicated, it must be “unzipped” so each strand can be copied. What enzyme does the unzipping?DNA polymeraseDNA helicaseDNA ligaseA short sequence from one strand of a DNA molecule reads [ AAT CCG GTG ]. What would the complementary strand be?AAT CCG GTGTTA GGC CACCCG AAT TGTUUA GGC CACTTU GGC CUCWhich of the choices in the previous question would be the mRNA molecule generated from the original strand of DNA? The process of ______________ generates a molecule of mRNA while the process of ___________ generates a polypeptide.DNA Synthesis | TranslationDNA Synthesis | TranscriptionTranscription | TranslationTranslation | TranscriptionWhat mRNA codon would be the promoter for protein synthesis? Use the chart above.UGAAGUAUGGUGWhat mRNA codon would be a terminator for protein synthesis?AUGUGAUGGGGGChoose the correct letter from the protein synthesis diagram to match these terms.1238250139065F00FThe mRNA template strand. An anticodon. A single amino acid attached to a tRNA. The polypeptide being generated by translation. A transfer RNA molecule. A ribosome. What part of the cell does DNA synthesis and transcription occur?The nucleusA ribosomeMitochondriaThe golgi.What part of the cell does translation occur?The nucleusA ribosomeMitochondriaThe golgi.Which type of DNA mutation is the result of a new nitrogenous base being added to the DNA strand?SubstitutionDeletionInsertionWhich type of DNA mutation is the least severe, because it does not disrupt the reading frame of the gene?SubstitutionDeletionInsertionWhich one of these activities would be the most likely to exposure you to a known mutagen?Drinking tap waterUsing an ultraviolet tanning booth.Smelling a dead animal.None of these. ................
