3 Vocabulary Words for Translation Translation decoding of mrna into protein Ribosome make protein, location of protein synthesis trna (transfer RNA) carries amino acids to the ribosome and matches them to the mrna Anticodon the complimentary 3 base pairs on trna Amino acid - the monomer building blocks, of proteins ( control cell process like traits) Peptide bond the bond that holds amino acids together Polypeptide Chain a long chain of amino acids Below is a diagram of trna (transfer RNA). Notice that the molecule is known as trna because it transfers Amino Acids (on top) to the ribosome.

4 Protein Synthesis: Translation The mrna leaves the nucleus and attaches to the ribosome in the cytoplasm. It attaches in groups of 3 bases, known as a codon. A second type of RNA, known as trna (transfer RNA) is found in the cytoplasm. This molecule has a unique folded structure, with a 3-base sequence known as an anticodon exposed along one side, allowing it to join with a matching codon from mrna. The trna also has an amino acid attached at one end. The amino acid that is attached is determined by the 3-base anticodon sequence.

5 Polypeptide Occurs in the cytoplasm

6 Work with a partner to answer the following questions. 1. What is the name and location of the process pictured above? Translation and cytoplasm 2. What does the t stand for in trna and what do they bring? Transfer and amino acid 3. When individual amino acids are brought to the, Ribosome what do they form? What bond is used? Polypeptide chain and peptide bond

7 Met Val Leu Tyr Arg Thr Stop Remember for amino acids, just write the first 3 letters. RNA contains the nitrogen bases: Adenine, Guanine, Cytosine and Uracil (U). Transcription occurs in the Nucleus Translation occurs in the Cytoplasm Go back and circle the amino acids and the peptide bond. Relabel the protein a polypeptide.

8 Protein Synthesis 1 Polypeptide

9 Answer the following CFUS based on the Translation portion of the diagram above. 1. What is the process to the above and where is it located? & Translation 2. Where does the mrna bond to trna? 3. What will eventually be synthesized? or Protein cytoplasm Ribosome Polypeptide Amino acid trna 4. What molecule is the monomer for protein?. 5. What molecule is transporting them? Ribosome Translation Amino Acids Protein

10 Independent Practice Answer all questions starting at the Independent Practice section. Work must be done silently and independently. No Talking. If you have a question or request raise a silent hand and be patient. For independent practice, today we will be working silently and independently for minutes.

11 Group Practice Review the questions answered during Independent practice. Go over each question. Each table member should explain why they selected their answer. Work must be done at a level ONE volume, which means I should not be able to hear you from my desk. Remain in your seat and only talk to people at your table. Make sure to keep conversations on topic. If you have a question or request raise a silent hand and be patient. For group practice, today we will be working for 10 minutes.
