Genomic DNA

Genomic DNA consists of a series of DNA containing the gene for the organism. The term "genomic DNA" is used to distinguish this type of DNA from different types of DNA, although many people think that everything is DNA into the genome, it is not really the case. Plasmids containing such DNA, the DNA, but that is not a part of the genome, but it can be hereditary and are passed on to future generations.

In humans, genomic DNA, 46 chromosomes, which are a comprehensive set of genetic data, including encoding DNA, to the expression of genetic characteristics and non-coding DNA that do not have this feature. Human genomic DNA was consistently in the Human Genome Project, to learn new things about the specific functions of different regions of the genome. Perhaps to find specific genes and further information can be used for the diagnosis and subsequent treatment of genetic diseases to be useful.
Genomic DNA from various other organisms of interest has been consistent. Animals that are the subject of genetic research, the flies, which are popular targets for sequencing. From the sequence information in hand, scientists can identify areas of genomic DNA is from individual to individual. These changes may provide clues as to have a better understanding of the genetic characteristics, including the regions of the genome in the expression of specific properties are involved, and expressing what go wrong, leading to congenital anomalies.

Many organisms have a complete set of genomic DNA in almost every cell. Determined in the cell, the various operations, which part of the genome is active, the body can create the differentiated cells and the regulation of cell function. Sometimes this rule is not as planned, can lead the development of malignant tumors and other problems are both genes are not correctly expressed, he said, when they should not be, or not at all expressed. A detailed study of the genomic DNA of an issue of worldwide interest in the field of bioinformatics as a study for the quantitative analysis and data from the study of different genomes known to be produced.Researchers can do things such as manipulation of genomic DNA to learn more about the regulation and function study of the human genome, and the creation of databases of the genome that can be shared by other researchers. The cooperation can be the key to solving the genetic puzzle, because the enormous size of the genome, it is technically impossible for a scientist to achieve significant progress.
