DNA -What is it?

Which of the following is not a component of DNA?

• 5 Carbon Sugar
• Phosphate Group
• Carbon Base
• Nitrogen Base

Which of the following is not a nitrogen base found in DNA?

• Thymine
• Uracil 
• Guanine
• Adenine

What is the significance of the sequence (order) of the Nitrogen Bases in DNA?

• The order of the Nitrogen Bases determines the number of chromosomes present in an organism.
• The order of the Nitrogen Bases determines the traits that an organism will possess (have).
• The order of the Nitrogen Bases determines the gender of an organism.
• The order of the Nitrogen Bases determines whether an organism is abiotic biotic.

Which of the following would be determined by the order of the Nitrogen Bases in your DNA?

• Your Gender.
• The Number of Chromosomes you have.
• Your hair color.
• The number of siblings you will have.

The twisted ladder shape of DNA is known as a

• Double Helix
• Triple Helix
• Single Helix
• Triple Helix

Assume that you have straight hair and your sibling has curly hair. What accounts for this difference?

• You have DNA and your sibling does not.
• The your sequence of nitrogen bases is different than your sibling.
• Your sibling has a weave. 
• Your sibling has a genetic mutation.
