Protein Synthesis Fill in the arrows with the correct process.Word Bank:TranscriptionTranslation Transcription Translation Protein Synthesis- Translation Watch this short video to review the steps of Protein Synthesis before answering the questions below. How are proteins made? Step 1:mRNA strands are transcribedfrom DNA in the nucleus of the cell, because the DNA is too big to leave the nucleus. The process of synthesizing a protein is called translation In other words, it translates the message carried on the mRNA into proteins. This occurs at ribosomesin the cytoplasm of a cell. Step 2:The mRNA must be translatedinto a protein. mRNA is read threeletters at a time, this three letter pair is called a codon. tRNA brings amino acidsthat match the codons from the cytoplasm to the mRNA. The Amino Acids then bind together to form a protein. Label Label the different parts the the tRNA.Word bank: Codon, Anticodon, Amino Acid Amino Acid Anticodon Codon How to read a Codon Chart Watch this video before attempting the practice problems below. Codons and Anticodons During translation, tRNA anticodons match to mRNA codons. Each tRNA molecule can carry one particular amino acid. The amino acids are joined to form a polypeptide.In the following diagram, number the four tRNA anticodons in the order in which they should appear to match the codons in the mRNA strand. 2 4 3 1 Wheel of Codons and Amino Acids Write the name of the amino acid that corresponds to each mRNA code. The first one has been done for you. mRNA Code (Codon) Amino Acid AAA Lysine GCG Alanine GAU Aspartic acid GAA Glutamic acid UAG Stop Which twomRNA codons correspond to histidine? (use the codon wheel) CAU CAA CAG CAT CAC How many different mRNA codons correspond to arginine? 1 2 3 4 5 6 Putting It All Together: Transcription and Translation Use either codon chart to transcribe and translate the following DNA sequence:**Remember** First you must transcribe DNA into RNA (A-U, C-G) DNA RNA Codon Amino Acid GGC CCG Proline CAT GUA Valine TTC AAG Lysine GAT CUA Leucine TTG AAC Asparagine AGC UCG Serine GAT CUA Leucine CCA GGU Glycine TAG AUC Isoleucine GCT CGA Arginine TCA AGU Serine ACT UGA Stop
