2. Why do you think they are studying DNA????

6. GO to Google Classroom and click on the link at the top of the page which will take you to the STEMscopes log-in page Enter your user name and password (I will give this to you) (I will give this to you)

7. Click on the Engage Student Materials link on your page. You will use this document as you rotate through the five stations at the back of the room, answering questions when needed.

11. Station 1: The Genetic Book of Life For this activity, you were ask to make an analog between DNA and the “Genetic Book of Life” Genome: Chromosome: DNA strands: Genes: Base-pairs: Book Chapter Sentences Words Letters

12. Station 2: Patterns in DNA What patterns did you observe in the molecule? twisted shape, repeating units of phosphates and sugars. a pattern of nitrogen bases only pairing with certain ones. one side begins with 5’ and ends with 3’. The other side starts with 3’ and ends with 5’.

13. Station 3: Who Am I? In this activity, you matched the term, description, and image of the parts of the DNA molecule. Term #1: Term #2: Term #3: Term #4: Term#5: Double helix Gene Hydrogen bond Chromosome Nucleotide

14. Station 4 Reading Charts What trends or patterns can you see? Adenine and thymine have the same percentage amount. Guanine and cytosine have the same percentage amount.

15. Station 4 Reading Charts Predict the percentages of bases from the information in this chart. 23 27

16. Station 5 DNA Structure What are the three components of a nucleotide? A phosphate group, a 5-carbon (pentose) sugar, and one of 4 nitrogenous bases. What types of bond connect the nitrogenous bases? Hydrogen bond What are the four nitrogenous bases found in DNA? Adenine, guanine, cytosine, thymine What molecule does the nitrogenous base bond to? The deoxyribose sugar Describe any patterns you see regarding the nitrogenous bases. Nitrogen bases always pair with a certain base. A pairs with T, and G pairs with C.
