1. Try this … What do a person, a tree, a monkey, a flower, an ant, a lizard, a snake, a dinosaur, a shark, a frog, a dog, a cat, a bamboo, a snail, a crocodile, a lion, a bear, an amoeba, an algae a fish, bacteria, mushroom and a beetle have in common?

2. That's right !They're all made of trillions tiny … CELLS

3. But if all living things are made of cells, what makes each one unique?

4. Each living thing is UNIQUE because of the DNA but what is DNA?

5. DNA The Blue Print Of Life

6. OBJECTIVES: 1. describe the composition ans structure of the DNA molecule 2. make a simple model of the DNA molecule 3. explain the nitrogen base pairing in DNA

7. Activity : Making A DNA Model Pair Work Pair Work Given the following materials, Make a simple DNA model. Materials: construction paper cut outs construction paper cut outs Scissors Scissors Scotch tape Scotch tape Hard plastic strips (to be provided by the teacher) Hard plastic strips (to be provided by the teacher) Pair the base cut outs and attach these in between the two plastic strips. You will be given 2 minutes for this.

8. Guide Questions for the DNA Model Activity : Describe the model you have made. Describe the model you have made. How are the base pairs arranged? How are the base pairs arranged? How did you know which one should be paired with the other? How did you know which one should be paired with the other? What does the plastic strips represent? What does the plastic strips represent? If we move the DNA model sideways how does it look like? If we move the DNA model sideways how does it look like?

11. Deoxyribonucleic Acid Is a nucleic acid found inside the chromosomes. It is made up of two strands ( double helix ) Basic unit: nucleotides made up of : 1.Deoxyribose sugar 2.Phosphate group 3.Base

12. NUCLEOTIDE Deoxyribose Sugar

16. Hydrogen bond

17. To Sum Up…

18. “I am fearfully and wonderfully made.”

19. How can we make proteins out of the DNA strand, Francis ? We’ ll find that out tomorrow, James
