Protein Synthesis: Transcription and Translation To better understand the process of protein synthesis, you will perform the work done by your enzymes to transcribe DNA into mRNA and then identify the final polypeptide chain of amino acids. Instructions: 1. Write down the corresponding mRNA sequence based on the given DNA sequence, in groups of three (codons). Remember that mRNA has Uracil (U) instead of Thymine (T). 2. Using the table, find the amino acid that matches the codon on the mRNA. A polypeptide chain usually starts with Methionine (Met) and ends with a Stop codon. 3. Write the first letter of each amino acid and find the secret message! Example: DNA: TAC - AGG - TCC - CCG - GGT - AGT - CTG - AGA - TTC - ATC mRNA: AUG - UCC - AGG - GGC - CCA - UCA - GAC - UCU - AAG - UAG Amino Acids: Met - Ser - Arg - Gly - Pro - Ser - Asp - Ser - Lys - Stop Sequence: DNA: TAC - CGT - CCC - TAA - ACG - GAT - TCT - TAC - AAG - ACA - TTA - TGA - TCA - ATT mRNA: Amino Acids: Message: __ __ __ __ __ __ __ __ __ __ __ __ __ 1st letter Second Letter c A uuu | Phe | ucu uau | tw |ucu | cys |u uuc ucc | ser | UAC uGc c UUA | Ley |UCA UAA Stop [UGA stop|A uUG ucG UAG Stop |UGG Trp |G cuu ccu cau | His | cou U cuc | Leu|}ccc | Pro | cac coc | arg |c CUA CCA CAA | Gin |cca A cuc cce CAG cGG G AUU ACU AAU | Asn |aGu | Ser |U auc | tle |acc | tr | AAC AGC c AUA ACA AAA AGA A L Ar AUG jet | ACG aac | |ace | “9 le6 GUU GCU Gau | Asp | Gou U GUC | yal) |} GCC | ala | GAC GGC | Gly |¢ GUA GCA GAA | gi | GGA A GUS GCG GAG GGG G srd letter
