A Unique Creation: Self-Replication of DNA
                   As we know, cells multiply by dividing. While the human body is
              initially composed of a single cell, this cell divides and reproduces itself
              many times over in a ratio of 2-4-8-16-32...
                   What happens to DNA at the end of this dividing process? There is
              only one DNA chain in the cell. However, it is evident that the newly
              formed cell will also require a DNA. In order to fill this gap, DNA
              completes an interesting series of operations, every phase of which is a
              different miracle. Finally, soon before the cell divides, it makes a copy of
              itself and transfers this to the new cell.
                   Observations of cell division show that the cell has to reach a specific
              size before dividing. The moment it exceeds this particular size, the
                            division process automatically starts. While the shape of
                                the cell begins to get smoother so as to accommodate
                                 the division process, DNA starts to replicate itself as
                              mentioned earlier.
                                   This means that the cell "decides" to divide as a
                                whole and the different parts of the cell start to act in
                                accordance with this decision. It is evident that the
                                cell is devoid of the consciousness to accomplish such
                               a collective action. The division process starts with a
                               secret order and the entire cell, including DNA, acts on
                              this order.
                                       First, DNA divides into two to replicate itself.
                                      This event takes place in a very interesting
                                      manner. The DNA molecule which resembles a
                                      spiral ladder divides into two like a zip from
                                      the middle of the rungs of the ladder. From now
                                      on, DNA divides into two portions. The missing
                                    halves (replicates) of both of the two portions are
                                     completed with the materials present in the
                                      milieu. In this way, two new DNA molecules
