… Summary of DNA Article, 2 pages
In the article author Nell Boyce discusses how deoxyribonucleic acid or DNA has achieved the status of “life’s master molecule.” This is because DNA holds the genetic material inside the chromosomes of every living cell.
This year marks the 50th anniversary since chemists James Watson and Francis Crick deciphered how DNA’s structure could hold the secrets of heredity in its unique structure. Watson found that the key parts of DNA linked together in a specific pattern – adenine (A) bonded with thymine (T) and cytosine (C) bonded with guanine (G).

… scientists who are studying how lifeless chemicals eventually gave rise to DNA-centered life.
DNA also has numerous uses outside pure biological research. DNA has helped cure deadly diseases and created new animal species. The unique chemical has also helped catch criminals and freed innocent people from death row.
Fifty years after Watson and Crick made DNA a household word, research into the chemical’s properties and potential continues. The National Aeronautics and Space Administration (NASA), for example, sponsors research how life could evolve in other worlds. Towards this, scientists are experimenting with structures other than the familiar double helix …
