  1. DNA Deoxyribonucleic Acid

  2. What isDNA? It is the genetic material that makes up all cellular organisms and most viruses.

  3. Where do you findDNA? In the nucleus of every cell in a living organism. Click the Hyperlink to view an interactive cell activity.

  4. Does DNA have a special job? It is a molecule that provides instructions (blueprints) for building different pieces of a cell.

  5. What does aDNAmolecule look like? It takes on the form of a twisted ladder shape that scientists call a “double-helix”

  6. Why are the rungs of the “double helix” of theDNAdifferent colors? Each color represents a letter of the DNA alphabet: A, C, T, and G

  7. Why are the rungs of the “double helix” of theDNAsplit? The DNA alphabet letters bond together: A always bonds with T C always bonds with G

  8. What do the letters of theDNAalphabet represent? A = adenine T = thymine C = cytosine G = guanine These are all called BASES
