1. Get out your spirals
Write the Learning Goal & critical question in the top section of your spiral.
Then answer the warm up question.
Critical Question: What are the 6 different components of DNA?
Warm Up Question: Where is DNA located in a prokaryotic cell? Eukaryotic cell? What’s it’s function?
HINT: Look at your cell diagrams.
PO 1. Analyze the relationships among nucleic acids (DNA, RNA), genes, and chromosomes.
MARKERS AT EACH TABLE!!

2. Warm Up Question Where is DNA located in a prokaryotic cell?
Eukaryotic cell?
What’s it’s function?
In the cytoplasm (free floating)
Inside the nucleus
Controls the cell’s function
Because it contains the cell’s DNA 

3. Cellular Processes DNA 
Goal: Remember the shape and components that make up DNA and their relation to each other

4. Genome Is a COMPLETE set of an organisms DNA
You have 100 trillion cells in your body
Each has the exact same genome inside the nucleus
If pages in a book represented one cell’s genome, the book would reach 65 ft high
If you extended all 100 trillion of your cells’ genome you could reach the moon and back 6,000 times
[(250 days) (8 months)]

5. How does all that DNA fit inside an organism?
All organisms have a certain amount of DNA that carries instructions necessary for life (genome).
Where is DNA located in bacterial cells?
How is DNA packaged into a cell?
discuss possible answers with shoulder partner  
Working with the person across from you, fit the “DNA” inside the prokaryotic cell.
How did you get the DNA packed into the cell?
“Prokaryotic Cell”
Unused DNA (or genes) gets twisted and twisted and twisted around itself until it is compacted and small enough to fit inside a cell.
5 minute Timer
“DNA”

6. So what is DNA? & Where is it?
DNA – DeoxyriboNucleicAcid
Genetic material that carries instructional information for a cell’s function and it’s
passed on from generation to generation
It’s found
in the form of chromatin (tangled mumbo jumbo)
Inside the nucleus
Tangled string and compact string

7. What does a DNA molecules look like?
A twisted ladder
Created by repeating subunits called Nucleotides
Nucleotide
Nitrogen Base
The rungs of the ladder
5 Carbon Sugar (deoxyribose) where the rung meets the side of the ladder
Phosphate Group
The space in between the rungs on the side

8. What the twisted Ladder Means
Nucleotide
Nitrogen Base
Adenine
Thymine
Cytosine
Guanine
5 Carbon Sugar (deoxyribose)
Phosphate Group
Draw Here
A=T
C=G
2 hydrogen bonds
3 hydrogen bonds

9. The Hand of DNA Draw the structures of DNA onto your hand
Nitrogen Bases
Adenine- binds to Thymine
Cytosine- binds to Guanine
Guanine- binds to Cytosine
Thymine-binds to Adenine
Phosphate – bonds to the 5th carbon of the sugar
Deoxyribose Sugar- 5 carbon sugar

10. Discuss these questions with your shoulder partner
Where are the sugar and phosphate located?
Where are the nitrogen bases located?
What letters pair up?
Observe the 5’ and the 3’
What direction does it run in relation to your thumb?
Just like you read left to right, DNA is read from 5’ to 3’

11. What are the 6 components of DNA?
Use this time to answer the critical question as 1 of your exit tickets.
What are the 6 components of DNA?
When you have answered the critical question.
Grab and correctly color the DNA strands

12. DNA Replication

13. DNA Replication Process
1. An Enzyme (Helicase) breaks the hydrogen bonds (unzips) the double stranded DNA
Helicase T G G T A C A G C T A G T C A T C G T A C C G T

14. Matching bases of DNA & RNA
Double stranded DNA unzips
Helicase T G G T A C A G C T A G T C A T C G T A C C G T

16. Exit Ticket Describe the overall shape of the DNA molecule.
How many strands of DNA are in one molecule?
What structures of DNA does the - palm and - thumb represent in your “Hand of DNA” activity
