  1. Seats: period1

  2. Seats: period5

  3. Catalyst 4 minutes! • How many chromosomes do you receive from mom? Dad? • How many chromosomes does a human have in somatic cells? Gametes? • Name 1 example of a genetictrait that could be passed from parent to child. • Fun Fact! If all the DNA in your body was joined together, how far would it stretch? • From your head to your toes • From Milwaukee to Cape Town, South Africa • From one side of Miss Andrews’ desk to the other • From the earth to the sun and back - 200 times!

  4. 100.B • 1: Raise a hand • 1: Exemplary answer in sentence • 1: Exemplary answer with thought • 1: Demonstrate “North Star” traits • 3: 100% seated before the bell • 3: “Ready for your attention” • 3: Lab /activity clean up • 5: 100% on task during practice • 5: 80% exit ticket average Music on Friday!

  5. Exit Ticket 4 minutes! 4 minutes! • You may use your assignments! • You must work quietly& independently. • Talking will NOT be tolerated. BIG goal = 80% 0

  6. 100.B love it or hate it! head phones! hot seat ! head phones! hot seat ! hot seat !

  7. Objectives • Agenda • Catalyst 5 • DNA Intro 15 • TedEd 10 • Twist Up! 20 • We are learning about… • Describe the basic structure of DNA, and describe its function in genetic inheritance. • We will be successful when we can… • Identify the main components of DNAin a model. sperm + egg = DiPLoiD

  8. I got it from my momma! • Blue eyes (E, e): Blue-eyed persons (e) lack coloring in the iris of the eye; individuals with other color eyes (E) have iris coloring. • Tongue rolling (R, r): Some people can roll their tongues (R); non-rollers can never learn to roll their tongues (r) . • Widow's Peak (W, w): Individuals results in a V-shaped front hairline (W); recessive individuals have straight hairlines (w). • Hitchhiker's thumb (H, h): people with recessive DNA can bend their thumb back to a 90° angle (h); the dominant condition (H) yields thumbs that cannot bend more than approximately 30°.

  9. What is DNA? • Deoxyribonucleic Acid • De-oxy-ribo-nu-cleic acid • What does DNA do? • Stores genetic information  traits • Provides a code to make proteins • Where is DNA found? • In the nucleus of allcells

  10. What does DNA look like? • Shaped like a twisted ladder  called a double helix • DNA is made up of nucleotides • Nucleotides are made up of • Phosphate • DeoxyriboseSugar • Nitrogen Base

  11. Close up! Hydrogen bonds Base Pairs = Ladder Steps Phosphate + Sugar = Backbone

  12. DNA Structure • DNA has 4 types of bases • Adenine = A • Thymine = T • Guanine = G • Cytosine = C • Adenine only pairs with Thymine (A & T) • Guanine only pairs with Cytosine (G & C)

  13. Quick Check! One strand of DNA has the base sequence A-G-A-T-T-C. What is the base sequence of the parallel strand? T – C – T – A – A – G You try! CGCCAT AATTACA TTAATT GCGGTA TTAATGT AATTAA

  14. Fun Fact! If all the DNA in your body was joined together, how far would it stretch? From the earth to the sun and back - 200 times!

  15. Sum it up… • Your genes code for traits • Example: eye color, tongue twist • Genesare made up DNA • DNAcoils into chromosomes • Chromosomes are found in the nucleus of all cells

  16. Ted Ed

  17. Twist Up! 15 minutes! • Do NOTeat until you get a signature! • Answer ALLquestions using complete sentences • Clean up ! ! ! • This assignment is due at the end of the period

  18. Test Score WARS • Period 5 • Noel* • Kiala* • Nakerie* • Period 1 • Auziauna* • Victor* • Shamena* • Shantiera* • Kiara* • Queen* Did YOU take the test? FRIDAYis the last day! Period 1 64% Period 5 59% test corrections due FRIDAY! Dashawn ! Daniel !

  19. Turn it in 
