6. Essential Question What are the components of DNA? Standard B.6A – Identify components of DNA, and describe how information for specifying the traits of an organism is carried in the DNA Pg 40

7. A lesson from Jurassic Park...

8. There are 4 kinds of nitrogenous bases in DNA. Adenine, Guanine, Cytosine, & Thymine

9. In a strand of DNA, adenine and thymine pair together while cytosine and guanine pair together. This pairing of bases is known as base pairing. Hydrogen Bonds

10. The differently shaped bases are bonded together antiparallel to one another (5’  3’) 5’ 3’ 5’

11. Sage and Scribe Can you draw a picture of DNA using 6 nucleotides?

12. Watson and Crick discovered the true shape of DNA. The shape of DNA is a double helix. A double helix looks like a twisted ladder or a spiral staircase.

13. DNA molecules in prokaryotic organisms are found in the cytoplasm. The DNA molecule in a prokaryotic organism is circular in shape.

14. Eukaryotic organisms possess 1000X more DNA than prokaryotic organisms. Eukaryotic DNA is generally located in the nucleus in the form of chromosomes. All eukaryotic organisms do not carry the same number of chromosomes.

15. Chromosomes are not clearly visible during most of the cell cycle. When the DNA is “unraveled” and doing its job, it is known as chromatin. However, during mitosis (M phase), the chromatin coils and condenses to form chromosomes.

16. Important to Remember: All living things have DNA! Scientists refer to this as a “common genetic code” The sequence of bases matters! The order determines the organism.

17. Think-Pair-Share: How do you think DNA copies itself?

18. Let’s build a DNA molecule….

19. DNA ModelPage 41 Essential Question: Question Column 1.How do the bases pair up in the DNA model? 2.How does your model help you figure this out? 3.What type of bond is found between the bases? 4.What is the monomer for DNA? 5.What are the 3 components in a nucleotide? 6.What are the components of the DNA backbone? 7.How many A bases are in your model? Is the number of T bases the same or different? Why? 8.Which portion of the DNA molecule differs for the different types of genes? 9.How has the knowledge of DNA structure benefited society? (Think about what you have read in the newspaper or magazines, seen on TV, for example the popular crime shows like CSI.) 10.Explain why models are useful to scientists. L1 – Identify…… L2 – Sort…….. L3 – Hypothesize……… 1.Summary - must be 41 words and include the following words. DNA nucleotide antiparallel nitrogenous bases twisted ladder What are the components of DNA?
