Codon to Amino Acid Chart Answers

Worksheet-Determination of Protein Amino Acids from M-RNA's Codon chart. Name Part 1 "Amino Acid/codon Wheel" Instructions: The "Wheel" at the right shows you how to determine which amino acid goes with which m-RNA codon sequence. To decode a codon, start at the middle of the circle and move outward. 1. Identify the amino acids what will be produced from the following m-RNAs codon: a. AAC Asparagus b. Ucu Seane . GAU Apach d. CCC Proline 2. What would the codon sequence (s) be for: Alanine Pro Date Key slanine GU Per GU Tryptophan Arginine G AC CUG Serina Lysine Leucine? UUR NUG CUU CUC сил, Valine? CUE, GUR GUE, GUT CUS тооsine 3. What are the m-RNA's stop codons: UCIA, LUAA, LAG A GIACUDACUOAC Threonine Machionine sucine Glutamine Arginine Serine ? Arginine, Tyrone ανακ 4. What amino acid sequence would be made from the mRNA sequence CGQUAUAGC Part 2 "Amino Acid/codon Chart" Instructions: The "Chart" at the right shows you how to determine which amino acid goes with which m-RNA codon sequence. To decode a codon, start with the First Base, then the Second Base, and finally the Third Base. 1. Identify the amino acids (you can get the full name from the wheel) what will be produced from the following m RNAs codon: First Base UCAGUCAG UCAG UCAG Third Base Second Base U C A G Phe Ser Tyr Cys Phe Ser Tyr Cya U Leu Ser Stop Stop Leu Ser Stop Tip Leu Pro His Arg Lou Pro His Arg C Leu Pro Gin Arg Lou Gh Pro Ar Ile lle The Asn Ser lle Thr A Asn Ser Thr Lys Arg Met Thr Lys Arg Val Ala Asp Gly Val Ala Asp Gly G Val Ala Glu Gly Val Al Glu Gly mRNA sequence GODATATCG CHAU AUAGC Sume! GOOATATCG CGC UAN AGC Arginine, Tyrioune Serine Arginine, Tyassine, Serine a. GUA VAL 6. UUU C. CAC HIS Phe d. UAA Stup 2. Suppose the DNA sequence GCTATATCG was changed to GCGATATCG. How would the products of transcription and translation be affected? Amino acid sequence Name Chapter Per Date Protein Synthesis Worksheet Protein synthesis is a complex process made up of the 2 processes transcription and translation, in this activity you will trace the steps that are involved in protein synthesis. A. Transcription Protein synthesis begins with DNA in the nucleus. Transcription takes place in the nucleus of the cell. During transcription messenger RNA (mRNA) reads and copies DNA's nucleotide sequence in the form of a complimentary RNA strand. Then the mRNA carries the DNA's information in the form of codons to the ribosome. Codons are a 3 nucleotide sequence in an mRNA strand. At the ribosome, amino acids will be assembled to form a polypeptide, which will become a protein. Below is a DNA sequence. Write the sequence of mRNA codons that would result from the transcription of the DNA sequence. DNA 1 ACA 2 ATA 3 TAG 4 CTT 5 TTG 6 ACG 7 GGG 8 AAC 9 CCC 10 ATT UGU UU AUC CIAA AAC UGC em L WAA B. Translation Translation takes place on the ribosome. For translation, another type of RNA called transfer RNA (IRNA) is needed. tRNA is a molecule made up of 3 nucleotides called anticodons. Anticodons are complimentary to the codons of mRNA. Attached to the tRNA anticodons are amino acids. During translation a IRNA anticodon will bind to a specific mRNA codon and bring with it the specific amino acid coded for. As IRNA bring amino acids, the amino acids bond together forming polypeptide chains, which will form proteins. Rewrite your mRNA sequence from part A. Using the amino acids table, determine the sequence of amino acids based on your mRNA strand. Use hyphens (dashes) to separate amino acids. tRNA: A Auc lutam систe сес UNG GETEG UDA link ine WP A aid Second G In Code U C Lysine Lysine Arginine Isoleucine Threonine A Arginine Methionine Threonine Asparagine Serine Isoleucine Threonine As Serine Threonine Glutamic acid Glycine Valine Alanine Glutamic acid Glycine Valine Alanine G Aspartic acid Glycine Valine Alanine Aspartic acid Glycine Valine Alanine STOP STOP Leucine Serine STOP Trytophan Leucine Serine U Tyrosine Cysteine Phenylalanine Serine Tyrosine Cysteine Phenylalanine Serine Glutamine Arginine Leucine Proline Glutamine C Arginine Leucine Proline Histidine Arginine Leucine Proline Histidine Arginine Leucine Proline
