The nucleus of a cell contains the chromosomal DNA for an organism.The first stage of the process is the unwinding of old strands of the parent DNA molecule.Since each cell in an organism must have a complete compliment of DNA, all of the DNA in the nucleus must be replicated before a cell divides.DNA replication begins at specific locations in the genome called origins.Every person in this world is born with an unique identity. Earlier it was thought that this unique character was only abstract qualities like nature or behavior that distinguished a person. But the DNA fingerprinting process has proven that there exists material evidence which can distinguish between any two individuals in this world.Among the many new tools that science has provided for the analysis of forensic evidence is the powerful and controversial analysis of deoxyribonucleic acid, or DNA, the material that makes up the genetic code of most organisms.DNA Replication is required for all cell division.DNA replication begins with the "unzipping" of the parent molecule as the hydrogen bonds.
