                  was discovered to exist in the arrangement of nucleotides in DNA. This discovery provided no support for
                  the thesis that the data in the so-called junk DNA was assembled by chance; on the contrary, it supported a
                  superior Creation as the basis of life.

                       ingless by themselves perform important functions together and play a role in the meiotic divi-
                       sion.


                       Recently, scientists have discovered the functions of heterochromatin, one of the chromosome materials
                  formerly thought to be junk. This code is often repeated in DNA, and since its role in the production of any
                  protein could not be determined, it was long defined as meaningless.

                       Hubert Renauld and Susan Gasser of the Swiss Institute for Experimental Cancer Research comment
                  that despite heterochromatin's significant representation in the genome (up to 15% in human cells and
                  roughly 30% in flies), it has often been considered as "junk DNA," of no utility to the cell.            85
                       But the latest studies have revealed that heterochromatin has some important functions. Emile

                  Zuckerkandl of the Institute of Molecular Medical Sciences has this to say:

                       . . . [I]f one adds together nucleotides [DNA base pairs] that are individually nonfunctional, one may end up
                       with a sum of nucleotides that are collectively functional. Nucleotides belonging to chromatin are an example.
