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

• The two different cells become mutated
• The proteins expressed in each cell are different
• They actually have different DNA in the two types of cells.
• The genome of the different cells changes

When a human embryo is developing, the embryo produces a special type of hemoglobin not found in infant, child, or adult blood. Which of the following best explains how an embryo can produce a different type of hemoglobin from an infant, child, or adult?

• The embryo has different genes from the infant, child, or adult.
• Development and differentiation result in the loss of certain genes.
• Humans have genes for the different types of hemoglobin, which are expressed at different times.
• Aliens visited the human at different phases of their lives and changed them.
