DNA Structure and Function

According to Chargaff's rule, Cytosine always pair with

• Adenine
• Uracil
• Thymine
• Gaunine

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
