What isDNA? It is the genetic material that makes up all cellular organisms and most viruses.
Where do you findDNA? In the nucleus of every cell in a living organism. Click the Hyperlink to view an interactive cell activity.
Does DNA have a special job? It is a molecule that provides instructions (blueprints) for building different pieces of a cell.
What does aDNAmolecule look like? It takes on the form of a twisted ladder shape that scientists call a “double-helix”
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
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
What do the letters of theDNAalphabet represent? A = adenine T = thymine C = cytosine G = guanine These are all called BASES
