DNA's ribbon-like backbone is made of

• deoxyribose sugar and phosphate groups

• carbon atoms

• enzymes and hormones

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.
