Chromosomes are made of

• DNA
• RNT
• WWE
• DMA

DNA is a polymer made of:

• Nucleotides
• Ribosomes
• Purines
• Pyrimidines

What determines the code, or information, of a DNA molecule?

• the shape (structure) of the nitrogen bases
• the order (sequence) of the nitrogen bases
• the color of the nitrogen bases
• the frequency (number) of nitrogen bases

Deoxyribonucleic acid, a long, complex molecule that controls heredity

• inherited trait
• chromosome
• DNA
• pedigree

According to Chargaff's rule, there are equal numbers of certain nitrogenous bases in DNA due to base pairing. So if we were to inspect a molecule of DNA and 20% of it was composed of Cytosine, what percentage would be composed of Guanine?

• 20%

• 30%

• 40%

• 25%

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
