2. I can identify the location of DNA in a cell. I can describe the structure of DNA. I can identify the basic building block of DNA. I can list the 3 parts of a nucleotide. I can name the type of sugar found in DNA. I can list the possible bases found in DNA. I can identify which nitrogenous bases pair with which other bases. I can describe the process in which DNA replicates itself.

3. Cell Nucleus DNA Sugar Phosphate Nitrogenous Base Nucleotide Adenine Thymine Cytosine Guanine Replication

4.  If you were to stretch all your strands of DNA out, end to end, how long would it be?

7. Remember… In the cell there is the nucleus. This is the control center of the cell because it holds the organism’s DNA.

8.  DNA looks like a ladder that is twisted  This structure is called the “double helix”

9.  DNA is made up of 3 very specific parts: › S = sugar › P = phosphate › N = nitrogenous base

11. 1 Nucleotide = 1 Phosphate + 1 Sugar +1 Nitrogenous base Stacking millions of nucleotides one on top of the other allows for the twisted ladder shape of DNA.

12. 1 Nucleotide = 1 Phosphate + 1 Sugar +1 Nitrogenous base Notice that the name of the sugar in DNA is deoxyribose.

13. 1 Nucleotide = 1 Phosphate + 1 Sugar +1 Nitrogenous base There are 4 different options for the base.

14. Adenine Thymine

15. Guanine Cytosine

16. Thymine & Adenine always pair up. Cytosine & Guanine always pair up.

18.  DNA has to replicate (make a copy of itself) before the cell can divide and become 2 cells.

19. Step 1: The 2 strands of DNA separate

20. Step 2: A new strand of DNA is created base-by- base to complement each original strand

21. The replication continues until the formation of 2 new, complete DNA strands is complete

24.  What is the structure of DNA called?  What is the sugar in DNA called?  What base pairs with Adenine?  What base pairs with Cytosine?
