U5L3E1: DNA Function

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.

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. 

How is the instructions for your traits carried on a DNA molecule?

• Sequence of the nitrogen bases
• In the 5 Carbon Sugar
• In the bond between the phosphate and the sugar
• In the phosphate group

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

The sequence of bases in the DNA is most important for which of the following?

• Providing the instructions for the traits of an organism

• Preventing mutations from occurring during DNA replication

• Allowing the DNA to have the shape necessary for the replication

• Helping form the sugar-phosphate backbone of DNA molecules
