DNA, RNA, and Snorks
DNA, RNA, and SnorksDNA, RNA, and SnorksName _______________________Pre-Activity Review Questions:There are 2 parts to the process of protein synthesis. During the first part, DNA is “copied” or transcribed into mRNA. What is this process called? ____________________________During the 2nd part, mRNA is translated and used to hook on the correct amino acids. What is this called? _________________What gets made during the process of protein synthesis?______________________________Procedure: On the following pages you have been provided with a single strand of DNA for 4 different Snorks. Snorks are alien sea creatures that were discovered on planet Dee Enae in a distance solar system. Snorks only have one chromosome with eight genes.Part 1 - Transcription: “Copy” or transcribe each strand of DNA into mRNA in the table below.Part 2 - Translation: The very first mRNA codon is a start codon. It does not show up in the amino acid sequence. The DNA and mRNA tables have been shaded in to represent each gene. Write the amino acid sequence for each gene in the table labeled Amino Acid Sequences. Use the codon chart below to translate each mRNA codon into the correct amino acid. Then use Trait Descriptions chart to determine each trait from its amino acid sequence.CODON CHARTTRAIT DESCRIPTIONS CHART2nd LETTERGenesAmino Acid SequenceTrait Descriptions1st LETTER3rd LETTERGene 1body coveringval - ser - leuhairlessval - ser - lyshairyGene 2body styletyr - pro - glu - glu - lysplumpval - pro - thr - glu - lysskinnyGene 3legsleu - leu - leu - pro3 leggedleu - leu - ser - ala2 leggedGene 4head shapeala - val - valround headval - ala - alasquare headGene 5tailshis - iletailhis - hisno tailGene 6body pigmentser - pro - valblue pigment (hair/skin)val - phe - tyrred pigment (hair/skin)Gene 7eyesasp - ile - leu - leu - pro - thrsmall slanted eyesasp - ile - pro - pro - pro - thrlarge round eyesGene 8mouthval - asp - asp - alacircular mouthasp - asp - asp - alarectangular mouthGene 9earsphe - ser - glypointed standing-up earsphe - phe - glyrounded floppy earsGene 10armsarg - tyr - cyslong spaghetti like armsarg - arg - aspshort stumpy armsSnicker SnorkDNATACCAGTCGTTTATGGGGCTTCTCTTTGAGAATTCACGCCGACAACACGTAGTACAAAAAATGCTATAGAATGACGGGTGGCTGCTGCTACGGAAAAGACCCTCTATAACAATTMRNAAmino Acid Sequences:Gene 1Gene 2Gene 3Gene 4Gene 5Gene 6Gene 7Gene 8Gene 9Gene 10Trait Descriptions:Trait 1Trait 2Trait 3Trait 4Trait 5Trait 6Trait 7Trait 8Trait 9Trait 10Drawing of Snork based on Trait Descriptions:Snuffle Snork DNATACCATAGATTTCAAGGATGACTTTTCGAAGAGGAGGGGCAACGCCGAGTAGTGCATAAAATACATTAAGAAGACGGGTGTCAACTGCTGCGTAAGAGCCCATCTATAACAATTMRNAAmino Acid Sequences:Gene 1Gene 2Gene 3Gene 4Gene 5Gene 6Gene 7Gene 8Gene 9Gene 10Trait Descriptions:Trait 1Trait 2Trait 3Trait 4Trait 5Trait 6Trait 7Trait 8Trait 9Trait 10Drawing of Snork based on Trait Descriptions:Snapple Snork DNATACCAGTCGGAACAAGGGTGTCTTTTTGAGAATTCACGCCAACGCCGAGTGTAAAGAGGGCATCTATAAGGGGGGGGGTGCCTACTGCTGCGTAAGAAACCCGCGGCCCTGATTMRNAAmino Acid Sequences:Gene 1Gene 2Gene 3Gene 4Gene 5Gene 6Gene 7Gene 8Gene 9Gene 10Trait Descriptions:Trait 1Trait 2Trait 3Trait 4Trait 5Trait 6Trait 7Trait 8Trait 9Trait 10Drawing of Snork based on Trait Descriptions: Snoopy Snork DNATACCATAGGGAGATGGGGCTCCTTTTTAATAATGACGGGCGACAACATGTATAAAGAGGGCATCTATAAGAACACGGGTGTCAACTACTACGGAAAAGACCAGCGGCACTGATTMRNAAmino Acid Sequences:Gene 1Gene 2Gene 3Gene 4Gene 5Gene 6Gene 7Gene 8Gene 9Gene 10Trait Descriptions:Trait 1Trait 2Trait 3Trait 4Trait 5Trait 6Trait 7Trait 8Trait 9Trait 10Drawing of Snork based on Trait Descriptions: ................
