1. BIOLOGY 1-5-16 1 ST ENTRY TASK FOR CHAPTER 12 LEARNING OBJECTIVE: HOW DNA WAS DISCOVERED STRUCTURAL COMPONENTS OF DNA ENTRY TASK: WHAT TYPE OF BIOLOGICAL MOLECULE IS DNA? WHERE IN THE CELL DNA IS FOUND?

2. TODAY’S PLAN DNA STRUCTURE NOTES DNA STRUCTURE AND REPLICATION VIDEO (CRASH COURSE) HTTPS://WWW.YOUTUBE.COM/WATCH?V=8KK2ZWJRV0M

3. THINKING QUESTIONS HOW DO YOU THINK SCIENTISTS WERE ABLE TO DETERMINE THAT DNA WAS THE INHERITANCE MOLECULE THAT WAS PASSED FROM PARENTS TO OFFSPRING? (12.1)

4. HOMEWORK DUE TOMORROW READ SECTION 12.2 (PAGES 344-348), AND COMPLETE QUESTIONS FOR SECTION 12.2 IN WORKBOOK HANDED TODAY.

5.  THE BASIC UNIT OF THE DNA MOLECULE IS CALLED: NUCLEOTIDE

6. A NUCLEOTIDE IN DNA HAS THREE PARTS:  A RING-SHAPED SUGAR CALLED DEOXYRIBOSE  A PHOSPHATE GROUP  A NITROGENOUS BASE (SINGLE OR DOUBLE RING OF CARBON AND NITROGEN ATOMS)

7. Nucleotide monomers join together by covalent bonds between the sugar of one nucleotide and the phosphate of the next, forming a sugar- phosphate backbone.

8. NITROGENOUS BASES

9. THE BASES PAIR UP (A-T & G-C) FORMING THE DOUBLE HELIX FIRST DESCRIBED BY WATSON AND CRICK

10. EXIT TICKET WHAT ARE THE THREE MAIN PARTS OF A NUCLEOTIDE? DO A DRAWING OF THE MOLECULE

11. BIOLOGY 1-6-16 2 ND ENTRY TASK FOR CHAPTER 12 LEARNING OBJECTIVE: STRUCTURAL COMPONENTS OF DNA WHY DNA NEEDS TO BE COPIED (REPLICATED) ENTRY TASK: WHAT IS THE SEQUENCE OF NITROGEN BASES THAT WOULD MATCH THIS: ATGACCTT WHAT DO THE LETTERS T, A, G, AND C STAND FOR?

12. TODAY’S PLAN DNA POGIL

13. WATSON AND CRICK FRANKLIN Figured out the shape of the DNA molecule Used X-rays to take pictures Of DNA molecule

14. VARIOUS WAYS TO MODEL DNA STRUCTURE http://www.umass.edu/molvis/tutorials/dna/dnapairs.htm manipulate DNAhttp://www.umass.edu/molvis/tutorials/dna/dnapairs.htm

15. WHY DOES DNA NEED TO BE REPLICATED? TO REPLACE OLD CELLS FOR GROWTH REPRODUCTION (BACTERIA AND UNICELLULAR ORGANISMS)

16. REPLICATION IN 3 STEPS  DNA REPLICATION RESULTS IN TWO NEW DNA MOLECULES, EACH CONTAINING ONE NEW STRAND (RED) AND ONE ORIGINAL STRAND (BLUE)

17. BIOLOGY 1-7-16 3 RD ENTRY TASK FOR CHAPTER 12 LEARNING OBJECTIVE: HOW DNA REPLICATES ENTRY TASK: WHAT DO YOU THINK IS THE FIRST THING THAT NEEDS TO HAPPEN TO THE DNA MOLECULE IN ORDER FOR IT TO BE COPIED?
