8. DNA and Genes (Chapter 11)

9.  History of DNA 1800’s Mendel determined that offspring inherited traits from parents 1944 Biomolecule that was involved with heredity was DNA (originally proteins were thought to pass on traits because DNA was too simple)

10. Rosalind Franklin and Maurice Wilkins took diffracted photographs of DNA X-rays were passed through DNA crystals, the X-rays were bent by the atoms in the DNA molecule producing an image of the shape

11. 1953 Watson & Crick developed a model of DNA using the diffraction photographs Double Helix = DNA comes in 2 long strands that wrap around each other, “spiral staircase”

12. Turn to page 283 Look at figure 11.2 (don’t forget to read the caption!) Answer the following question and be ready to share with the class! 1. what is another analogy used for the shape of DNA (besides a spiral staircase)

13.  Why is DNA so important? DNA is known as “blueprint of life” DNA contains instructions for making proteins within the cell Genes are on our chromosomes, chromosomes are made of DNA

14. Turn to page 281 Read the paragraph with the heading What is DNA? Answer the following question and be ready to share! Answer the following question and be ready to share! 1. List 3 places in your body that contain proteins 2. Enzymes are a type of protein. Why do we need them?

16. Why is DNA so important? Important for all life on Earth, makes each individual plant or animal unique Helps us understand diseases better & find potential cures Better food crops

17. 2/13/15 BIOLOGY MRS.TURGEON “ You have brains in your head. You have feet in your shoes. You can steer yourself in any direction you choose.” – Dr. Seuss OBJECTIVES SWBAT: Identify the key components of DNA DO NOW: what type of chemical bond is between the complementary base pairs in DNA?

18. 2/13/15 BIOLOGY MRS.TURGEON REMINDERS: 1.Tutoring Tues & Thur after school(rm 309) 2. Field trip form must be turned in today 3. Foldable 11.1 due Tuesday, Feb. 17

19. TODAY’S ASSIGNMENT: 1.In the textbook, read section 11.1 2.Answer questions 1-5 in the section assessment on page 287 3.Each student completes your own questions 4.Turn in the questions and work on your foldable for 11.1 (12 entries minimum)

20. 2/12/15 BIOLOGY MRS.TURGEON REMINDERS: 1.Tutoring Tues & Thur after school(rm 309) 2. Field trip form must be turned in today 3. Foldable 11.1 due Tuesday, Feb. 17

21. TODAY’S ACTIVITY: 1.Work in POGIL groups 2. Put together DNA model according to instructions 3. You will turn in one model per group

22.  DNA Nucleotides DNA is a nucleic acid made from subunits called nucleotides Nucleotide = 3 parts: five-carbon sugar, phosphate group, nitrogenous base –Deoxyribose = the sugar in a DNA nucleotide

23.  How the Double Helix stays together Double Helix has two strands that twist together One strand of DNA is like one half of a zipper – –The backbone of the molecule is alternating phosphates and deoxyribose sugar – –The teeth are nitrogenous bases phosphates deoxyribose bases

24. One strand of DNA (half of a zipper) is a polymer of nucleotides One strand of DNA has millions of nucleotides

25.  Nitrogenous Bases DNA has four different bases CytosineC ThymineT AdenineA GuanineG

26. 2 kinds of Nitrogenous Bases Purines = double ring bases, A and G Pyrimidines = single ring bases, T and C

27.  Complementary Bases Nitrogenous bases on the 2 strands of DNA pair up with one another Cytosine pairs with Guanine with 3 (triple) Hydrogen Bonds Adenine pairs with Thymine with 2 (double) Hydrogen Bonds

28. Turn to page 283 Read the Problem-Solving Lab 11.1 Answer the 3 “thinking critically” questions. Write your answers on the back of your lazy notes. You have 5 minutes

29.  DNA Model
