Log on and use the website: http://learn.genetics.utah.edu/units/basics/tour/
1. Next, click on the link: What is DNA?
2. You will examine the inner working of the ear and what support the hearing function. Click next.
3. Within a single cell, the instructions that provide all the necessary information for a living thing to grow and function reside in
the _______________________ of the cell.
4. Click next to move on.
5. Where do these instructions for life come from? _____________.What is the full name? ______________________________
6. Click next to move on.
7. What is the shape of DNA? _____________________________. What two molecules make up the outside of the DNA
structure? ___________________ and _____________________. What part makes up the inside “rungs” of the DNA
molecule? ____________________. They are held together by ____________________bonds.
8. List the 4 letters that make up the “rungs” of the double helix. _______,_______,________,________
9. What are the base pair rules – how do these letters pair together? _____________________ and ____________________
10. Draw a segment of the DNA double helix: include the following labels – sugar, phosphate, nitrogen bases (A, T, G, G), Hbond.
11. Click next to move on. What do these 4 letters tell the cell?
12. The DNA stand is made of letters – observe the strand on the site. Copy the first 10 letters of the strand below
Strand 1:
Strand 2:
13. From the strand above use the correct base pairs to make a new complimentary strand underneath it.
14. Open a new window (do not close the one you are using) and use the web site:
http://learn.genetics.utah.edu/units/basics/builddna/
a. Find and Read introduction to “Build a DNA molecule”
b. Go down to the click and drag area and build a DNA molecule – use base pair rules
c. Repeat making a new DNA molecule sequence
d. Go back to the other web page and continue
15. What you will learn is that the letters make “words” and words make “sentences” – These sentences are called ___________.
What do genes tell us? _________________________________________________________________. What do proteins
do for the body? _____________________________________________________________________________________.
Click on the link, What is a gene?
16. What is a gene?
Click on the link, What is a protein?
17. Proteins are the ______________________that make all living things function.
18. How is a protein like a car?
19. Click next and learn more about proteins and pain signaling. (6 screens)
20. What type of protein is responsible for receiving signals and passing them along to other cells?_________________________
21. Cells use the information encoded in their _________________. Each gene gives the specific instruction of how to make a
___________________.
22. Transcription is a process that occurs in the ______________________of the cell. The DNA message is read and forms
__________ which is similar to DNA. Look at cell closely. Click next to see the animation – play again to understand
more.
23. Translation is a process that occurs in the _______________________of the cell. After the RNA is formed it carries the
genetic message and moves from the nucleus and is met by the _______________________ structure or the protein making
machine.
24. What happens at the ribosome? _______________________________________________________________________
25. What happens to the protein after it is made during the process of translation?
Play the DNA – Double Helix Game: Use the site: http://nobelprize.org/educational_games/medicine/dna_double_helix/
1. Click play to begin, wait to load
2. Read each frame to learn more about the DNA structure.
3. Your job is to create the DNA for 3 unknown organisms – trying not to make mistake in the helix
4. Click on organism 1 and play the base pair game – watch out its quick
5. Organism 1: Read the info about each organism – using the data to the right after your game. Number of
chromosomes________Number of base pairs (millions) _________Genes_____________What is organism 1?
________________________.
6. Click on organism 2 and 3 and play the game.
