Building Knowledge – Part 3



Building Knowledge – Part 2

Title

Step 1. Attempt the knowledge check for this portion of the unit. See bottom portion of this page.

Parts of the ,,,,,,,,,,,,,,,, Knowledge Check – Answer the knowledge check questions. They are located at the end of this document… If you are unable to answer the questions you must complete the knowledge building exercises, step 2. If you are able to answer the questions without any assistance you are ready to move on to the next portion of the unit, Building Knowledge part 2. Submit your work to your instructor via email for feedback.

You are encouraged to complete the knowledge check in a word document. However you are welcome to complete the knowledge check by printing the document and placing it in your biology binder OR complete the following in your biology lab notebook.

Step 2. Learning working from a message DNA to a Protein. For example, DNA message to the protein, melanin, skin pigment.

THIS IS THE CENTRAL DOGMA OF BIOLOGY. Take time to learn this process called Protein synthesis or transcription and translation.

Step 1 – Watching this amazing process happen.

Version 1 – Check your understanding by watching then completing the following online quiz.



AND/OR

Version 2 - OR Watch and participate in the online quiz.



Version 2 part 2



Step 3 - The players in protein synthesis

Worksheet - Coloring Protein Synthesis – Click on the link on the project 2 page.

Step 4 – Practice with Transcription and translation.

Transcription translation worksheet.

Step 5 - Application of your knowledge. You are welcome to complete this portion and submit it instead of doing step 6.

Step 6 - Showing what you learned

Correct the quiz using a different color (to show your learning) using what you learned the content. Never delete your work. Only use strike through (select the font you would like to change. Click on format, click on Font, click “strikethrough.”

Knowledge Check DNA to Proteins – Formative Quiz

DNA to Proteins….

1.. How is RNA different from DNA? ( A with U ** : G with C)

2. What is a mutagen? What are the causes of mutations?

3. What are the roles of the following molecules (protein synthesis): DNA, messengerRNA, ribosomalRNA, transferRNA? Draw a picture.

|DNA sequence |mRNA sequence |tRNA sequence |Amino Acid sequence |

| | | | |

|A T | | | |

| | | | |

|G C | | | |

| | | | |

|C G | | | |

| | | | |

|T A | | | |

18. Use the amino acid genetic code below for the following problem. Given the following coding strand of DNA, find the template strand, and the mRNA strand. Organize the mRNA by codons. List the anticodons of tRNA and state what the amino acid sequence. (8)
