                                                A single cell nucleus, invisible to
                                         our eyes, contains a DNA strip that is 4 me-
                                        ters (13.12 feet) long, packaged inside the
                                       nucleus in the form of groups known as
                                     chromosomes. The nuclei of the cells in your
                                  body contain a total of 23 chromosome pairs.
                            When chromosomes are magnified under an electron mi-
               croscope, the DNA molecule inside these chromosomes are seen to be
               compressed in a spiral form. Despite occupying a very small volume,
               this packaging system possesses a stunning data-storage capacity, as
               you'll see in a later chapter.
