Josh's DNA:
 * What are the 5 elements that make up DNA?
 * The 5 elements that make up DNA are Oxygen, Carbon, Hydrogen, Nitrogen, and Phosphorus.
 * Describe how long strands of double-helical DNA fit into the nucleus of a single cheek cell.
 * DNA wraps into a double helix, and it is then wrapped around a histone.
 * What was the purpose of using the cell lysis solution?
 * It messes up the outer membrane of the cell, causing the Cell to burst open, releasing the DNA.
 * Why does the DNA become visible once the alcohol is added?
 * DNA becomes visible due to the alcohol being added because the DNA is a polar molecule and the alcohol is a non-polar substance.
 * If DNA is so thin, how is it that we are able to see it during this simple lab exercise?
 * There is long strands to make it more visible, and the coloring from the drink.
 * What is the function of DNA from day to day?
 * DNA guides the cell in making proteins that make up our traits.
 * Give some examples of how DNA is used everyday.
 * It is used in jobs like crime solving, and doctors use it to find out what diseases you can get.
