The deoxyribonucleic Acid (DNA) technology was born in secrecy of the World War two but of later focus of science to biology. Initially, it was thought that DNA was a hidden force but it was discovered it contained the genes, the fundamental units of inheritance, the blue print of the cell's work. DNA engineers spilt open DNA, cut individual genes, transplanted them into bacteria or other cell and reproduced them a million times. From these experiments they can deeply understand diseases like cancer. It also offered unlimited opportunities to other industries to create or to contain different diseases traditionally killed by chemicals.

DNA basically can trace life to its origin and identifies its organizational structures. It traces to point that all living organisms now come from a single cell that over time aggregated in many complex ways to build them. Organism and objects form part of the wholes such as families, societies and civilizations.

The cell is the fundamental unit of living matter, or the first life form was a single celled organism and all subsequent evolved living species consists of a cell or cells. The cell is something like a factory. The first fundamental division of the cell is into two component parts-the nucleus and cytoplasm. This nucleus is like the office of the factory. They control the centre of the cell; the place where fundamental decisions are made just about what kind of work the cell is going to do.

Living cells have plenty of small molecules in them, such as water, salt, sugar and organic chemicals that performed specialized jobs as building blocks. However, the large molecules or macromolecules are characteristics of living matter. They are four of them, nucleic acid, protein, carbohydrates and fats. They give structural appearance and storage of energy a cell needs to grow

All these molecules are important one that is related to DNA is Nucleic Acid. They are made of nucleotides and are very complicated. The function of nucleic acid depends only on the linear order of the bases. They are the blue print or codebooks – useful only when translated. They have two parts, DNA and RNA. They are long chains of four building blocks and, the bases, and that order of the bases along the strands is how genetic information is stored.

The genetic codes can be read with four letters G, C and T. The codes are linearly structured and represent various chemicals and molecules that could decode to read the make up, and making of a particular cell. DNA information could be used to unfold an accurate copy of DNA's message made in RNA. The DNA acts as template and RNA as copy of the gene. As the gene engineers decode these makes to define a DNA of an organism, two things are easily determined. Human cells have to make tiny fractions and produce one cell like one stomach cell produce digestive juices. Other bacterium cell multiplies.

The Human Genome project open up new avenues for research to many possibility for human development but it also creates many question for how people to live their live. The issue of Genetic food, genetic human cloning and so forth is just becoming an ethical question of 21st century.
