BELL WORK
​HOW COULD THIS MOLECULE POSSIBLY HELP DETERMINE WHO YOU ARE? 

3 PARTS OF A NUCLEOTIDE:
ONE PHOSPHATE GROUP
ONE SUGAR (DEOXYRIBOSE / 5 CARBON)
ONE OF FOUR NITROGEN BASES: ADENINE, THYMINE,
GUANINE, OR CYTOSINE.










GOAL:  
INTEGRATE EVIDENCE TO DEVELOP A STRUCTURAL MODEL OF A DNA MOLECULE.

WHY?
SO WE CAN DISCUSS GENETICS, DEVELOP CURES, AND TRACE FAMILY TRAITS.











THINGS: YOU ALREADY KNOW:
1. DNA IS LOCATED IN THE NUCLEUS.
2. DNA FORMS CHROMOSOMES.
3. DNA CONTROLS A CELL'S FUNCTION.















Objective:
The Learner Will: Explain the structure of the DNA molecule.

​









WATCH AND RECORD 5 FACTS FROM THE VIDEO.

 












ACTIVITY 1:
In small groups, discuss and complete the graphic organizer worksheet...prepare to share your findings.

TODAY:
USE PAGE 422 AND 423 FOR HELP.
USE "P" FOR PHOSPHATE GROUP.
USE "S" FOR SUGAR.
DRAW A SQUARE AROUND A NUCLEOTIDE.
​DRAW A CIRCLE AROUND A BASE PAIR.

REMEMBER THIS "BASE-PAIRING RULE"
A BONDS WITH T / T BONDS WITH A
C BONDS WITH G / G BONDS WITH C

​

ACTIVITY 2: 
BIG GROUP / ONE FLASHCARD
THUMBS UP IF YOU KNOW THE ANSWER....PREPARE TO SHARE.

TRY THIS:
1. POINT OUT THE LOCATION OF TWO DIFFERENT TYPES OF BONDS IN DNA .
2. PREDICT THE MATCHING NUCLEOTIDES.

TICKET OUT THE DOOR: ON NOTEBOOK PAPER
YOU AND A CLASSMATE ARE LOOKING AT A DIAGRAM OF DNA.
YOUR CLASSMATE IS NOT CONVINCED THAT IT IS DNA.
EXPLAIN (WRITTEN EXPLANATION) TO YOUR CLASSMATE, THAT IT IS DNA IN THE DIAGRAM....3 REASONS MINIMUM.
----------------------------------------------------------------------
ASSIGNMENT:
DRAW AND LABEL A DIAGRAM OF DNA.
IT MUST INCLUDE:
2 DIFFERENT TYPES OF CHEMICAL BONDS,
4 DIFFERENT NUCLEOTIDES
*OVERALL LENGTH 7 BASE PAIRS
*ILLUSTRATE AN ANTIPARALLEL MOLECULE
*SHOW THE NUMBER OF HYDROGEN BONDS BETWEEN    
    COMPLIMENTARY NITROGEN BASES.
