1ST 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?
TODAY’S PLAN
• DNA STRUCTURE NOTES
• DNA STRUCTURE AND REPLICATION VIDEO (CRASH COURSE)
• HTTPS://WWW.YOUTUBE.COM/WATCH?V=8KK2ZWJRV0M
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)
HOMEWORK DUE TOMORROW
• READ SECTION 12.2 (PAGES 344-348), AND COMPLETE QUESTIONS
FOR SECTION 12.2 IN WORKBOOK HANDED TODAY.
 THE BASIC UNIT OF THE DNA MOLECULE IS CALLED:
NUCLEOTIDE
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)
Nucleotide monomers
join together by
covalent bonds
between the sugar of
one nucleotide and the
phosphate of the next,
forming a sugarphosphate backbone.
NITROGENOUS BASES
THE BASES PAIR UP (A-T & G-C)
FORMING THE DOUBLE HELIX FIRST
DESCRIBED BY WATSON AND CRICK
EXIT TICKET
• WHAT ARE THE THREE MAIN PARTS OF A NUCLEOTIDE?
• DO A DRAWING OF THE MOLECULE

2ND 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?
TODAY’S PLAN
• DNA POGIL
WATSON AND CRICK
Figured out the shape of the DNA
molecule
FRANKLIN
Used X-rays to take pictures
Of DNA molecule
VARIOUS WAYS TO MODEL DNA
STRUCTURE
•http://www.umass.edu/molvis/tutorials/dna/dnapairs.htm
manipulate DNA
WHY DOES DNA NEED TO BE REPLICATED?
• TO REPLACE OLD CELLS
• FOR GROWTH
• REPRODUCTION (BACTERIA AND UNICELLULAR ORGANISMS)
REPLICATION IN 3 STEPS
 DNA REPLICATION
RESULTS IN TWO
NEW DNA
MOLECULES, EACH
CONTAINING ONE
NEW STRAND
(RED) AND ONE
ORIGINAL STRAND
