DNA History

What does DNA do?

• a.  It carries genetic codes from parents to offspring.
• a.  It carries oxygen from the lungs to the body.
• a.  It tells you who you are.
• a.  It defines the organism.

What is the shape of a DNA?

• Double Helix
• Base Pairing
• The shape of you
• Hydrogen Bonding

Adenine, Cytosine, Guanine and Thymine are examples of

• DNA structure

• DNA bases

• DNA double helix

• DNA sugars

The sequence of bases forms the

• Genetic Code
• DNA base pair
• Double Helix
• Paired bases

What holds the DNA bases together?

• Hydrogen bonds
• DNA bases
• Double Helix
• Paired bases

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy

What are the three components of a nucleotide?

• sugar, hydrogen, nitrogen base

• sugar, oxygen, nitrogen base

• sugar, phosphate, nitrogen base

• sugar, phosphate, protein
