Respond to the questions and promptsin the orange boxes.Vocabulary:amino acid, anticodon, codon, gene, messenger RNA, nitrogenous base, nucleotide, ribosome, RNA,RNA polymerase, transcription, transfer RNA, translationPrior KnowledgeQuestions(Do theseBEFOREusing the Gizmo.)1.Suppose vou want to design andbuilda house. How would vou communicate vour design plans with theconstruction crew that would work on the house?Iwouldshow them mv designs and plans and communicate what I would want to do2.Cells build large, complicated molecules such as proteins. What do vou think cells use as their "design plans" forproteins?DNAGizmoWarm-upJust as a construction crew uses blueprints to build a house, a cell uses DNA asplans for building proteins. In addition to DNA, another nucleic acid, calledRNA,is involved in making proteins. In the JLVri and Prettin Sj'nrnesk Gizmo, vou willuse both DNA and RNA to construct a protein out ofamino acids.1DNAis composed of thenitrogenous basesadenine(A),cvtosine I.C),guanine (G), and thvmine(T). RNAis composed of adenine, cvtosine,guanine, and uracil i.Ui.Look at the SIMULATION pane. Is the displaved segment a part of a DNA orRNA molecule? How do you know?DNA -ithas thvmine, not uracil+ itisdouble stranded2RNA polvmeraseis a type of enzyme. Enzymes help chemical processes occur quickly. Drag the vellowRNApolymerase molecule onto the DNA strand.

This complementary strand iscalledmessenger RNA,or mRNA.Question: What:occurs during transcription?1P.yperimp-nt- Like DNA, RNA follows base-pairing rules. Experiment to find whichRNA nucleotideon theright side of the Gizmowillsuccessfully pair with the thymine at the top of the template strand of DNA.(NOTE: The DNA on the right side is the template strand.)Which RNA base bonded with the thvmine?Adenine2.Experiment: The next three bases on the DNA template strand are adenine, cytosine, and guanine. Use theGizmo to answer the following questions:A.Which RNxA base bonds with adenine?E.Which RNxA base bonds with cytosine?C.Which RNxA base bonds with guanine?3.Observe:In molecules of RNA, uracil takes the place of the DNA baseThymine4.Build: Continue building the strand of mRNxA until you have used all of the RNA nucleotides.What is the nucleotide sequence of the mRNA strand vou built?xAUGCUGxACCLIAG5.Applv: Suppose a template strand of DNA had the following sequence:T A CG G AT AACT AC C GG G TA T TCA AUracilGuanineCvtosineWhatwouldbe the complementary strand of mRNA?UGe c uC C AGUUPredict Howwoulda change to the sequence of nucleotides in a DNxA segment affect the mRNA transcribedfrom the DNA?Reproduction Far educatlaial use only.
