4B Protein Synthesis
I can use a model to illustrate how the structure of DNA determines the structure of
proteins (transcription & translation) and how those proteins carry out essential functions on life.

activity 5: whole class lecture
This is one of the few times this year that we will have traditional in class lecture with notes. Protein synthesis is a complicated process with a lot of details. We will be studying this concept together as a class. Please do not work beyond this point until AFTER the lecture. You may review or you may work on your Unit Project until the class is ready.
activity 6: ISN DiagramCopy the image below into your ISN. Then you will simulate the process of transcription and translation. Use the BOTTOM strand of DNA shown in the diagram. TRANSCRIBE that DNA template into an mRNA molecule (the gray line symbolizes the mRNA). Be sure to write the mRNA bases in the appropriate CODON groups (shown by the brackets). Then TRANSLATE that mRNA molecule into the correct AMINO ACID sequence. Have your instructor check your work when you are finished.

activity 8: wheel vs. chart(For this activity, you will work in PAIRS. Take turns. When it is your turn, say a 3 letter codon out loud. Your partner will then use the wheel and table below (or you may work from your paper copy if you wish) to tell you what amino acid that codon codes for. You must then tell them if they are correct or not. For the first round, each partner must use the WHEEL and answer correctly THREE TIMES. For each wrong answer, you must go again. For the second round, each partner must use the CHART and answer correctly THREE TIMES. Once you have finished practicing with your partner, call your instructor over to check your work.

activity 9: transcription & translation simulationFor this activity, you will work alone. Go to the link below. The interactive will walk you through the process of making a protein. At the end, enter your name and submit your score to your instructor online. Instructions for how to do this are in the game.

activity 12: The Latest ScienceNow that you understand the process of protein synthesis and how mRNA is used to move genetic information from the nucleus to the ribosome, and that the information carried in that mRNA gives rise to proteins in the body, let's see what doctors and scientists are doing with this knowledge.
