Biology Genetics Unit: Online Activities 1.) Go to the link: http://learn.genetics.utah.edu/content/begin/dna/ Run through the “What is DNA?” interactive. This will act as a review. A.) What type of cells are examined? _________________________________ B.) What molecule contains all the genetic material necessary for a cell to carry on all functions? _________________________________ What organelle is this found in? _________________________________ C.) DNA acts as a _________________________________for building different parts of a cell. D.) Which letters always pair with which letters? ________________________________________________________________________________ E.) What types of bonds join the letters that form the “rungs” of the ladder? _____________________________________________________________ F.) What do genes do? ______________________________________________________________ G.) What do proteins do? ______________________________________________________________ 2.) Go to the link: http://learn.genetics.utah.edu/content/begin/dna/builddna/ Run through the “Build a DNA Molecule” interactive. Do it until the popup appears. What is the interesting, and funny message that you received after a while of DNA building? (Keep on going! It may take more bases than you think to get to this pop up!) _________________________________________________________________________________________________ _________________________________________________________________________________________________ _________________________________________________________________________________________________ Referring to this same page, what are the three parts that make up a nucleotide? i. _________________________________ ii. _________________________________ iii. _________________________________ 3.) Transcription Activity http://learn.genetics.utah.edu/content/begin/dna/transcribe/ A.) Type in the correct letters. Write the original DNA sequence here: __________________________________________________________________ Write the letters that you typed in for the RNA strand here: __________________________________________________________________ B.) Now, you will be asked to select the 3 letter codon to start at by putting your cursor over it. Read below it and use the chart to complete this. Look for MET. (Codon for MET is AUG.) C.) Now, start dragging and dropping in the correct amino acids. D.) Good job. Now, after the STOP codon, you are done. What was the three letter sequence for the stop codon? _________________ 4.) Protein Synthesis Interactive through Wisconsin Learning http://www.wisc-online.com/Objects/ViewObject.aspx?ID=AP1302 A.) Click the “Next” button on the bottom right hand side of the white box. B.) How does the cell know to make a certain protein? ___________________________________________________________________________ C.) How is the gene, as part of the DNA, able to be read? ___________________________________________________________________________ D.) What type of strand are enzymes helping to make? ___________________________________________________________________________ What does uracil code for? ___________________________________________________________________________ E.) Where does the mRNA go after it has been transcribed? ___________________________________________________________________________ F.) What decodes the mRNA? ___________________________________________________________________________ How is the message read? ____________________________________________________________________________ G.) What does each codon stand for? ____________________________________________________________________________ H.) What are the two ends of a transfer RNA molecule (tRNA)? ____________________________________________________________________________ What binds to the binding site? _____________________________________________________________________________ I.) How is the specific amino acid brought to the correct place? _____________________________________________________________________________ J.) Where does this process get its energy from? ______________________________________________________________________________ K.) How do the amino acids link up? ______________________________________________________________________________ L.) After the entire message is read, what is formed? _______________________________________________________________________________ M.) What happens to the mRNA when protein production is complete? _______________________________________________________________________________ 5.) Watch this http://youtu.be/erOP76_qLWA You are to create narrations for this video in your own words. Watch the video and listen. Now, try to do it on your own and in your own words. Use this form: TIME 0:00 0:11 0:19 0:27 0:34 0:38 0:44 0:55 1:02 NARRATION “This is an animation that will show the full process of protein synthesis including Transcription, Translation, and the folding of Proteins.” “Here you can see the DNA molecule inside the nucleus. It is the DNA molecule that is responsible for all processes in the cell including the production of proteins.” 1:08 1:12 1:18 1:22 1:30 1:45 1:55 2:00 2:07 2:12 “And now, the newly folded protein can travel to other areas of the cell to serve important functions.”
