INTRODUCTION
DNA is present in the cells of living oranisms. The nuclei acid DNA or deoxyribonucleic acid serves as the genetic material in all living organisms as well as in most viruses. DNA is organized into genes and stores genetic information. DNA molecules are long, slender molecules that carry the heritable information of organisms on to future generations. Because of their size, it is impossible to see a single DNA molecule with the naked eye. It would take about 300,000 DNA molecules side by side to make a bundle as thick as a human hair. When subjected to certain conditions, it is possible to collect “large” amounts of DNA to make it visible. As part of the chromosomes, the information contained in genes can be transmitted faithfully by parents through gametes to their offspring. For the gene’s DNA to subsequently influence an inherited trait, the stored genetic information in the DNA in most cases is first transferred to a closely related nuclei acid, RNA or ribonucleic acid.

In eukaryotic organisms, RNA most ofther carries the genetic information out of the nucleus, where chromosomes reside into the cytoplasm of the cell. In the cytoplasm, the information in RNA is translated into proteins, which serve as the end products of most all genes. The process of transferring information from DNA to RNA is called transcription. The subsequent conversion of the genetic information contained in RNA into a protein is called translation.

DNA molecule exists in cells as a long coiled structure...
