Plasmids can either be bacterial, viral, bacterial artificial chromosomes, yeast artificial chromosomes, or artificial cosmids, depending on the host organism of choice. Plasmids can also be classified based on its function, such that there is a certain set of vectors that can be used if the goal of the experiment is to only propagate the gene, as is the case for this particular study. However, vectors that allow expression of particular gene into the corresponding protein are also available as well.
The growth in the population of host cells containing the recombinant DNA molecule will also result to the replication of the gene clone. As added optimizing measure, aside from the G6Pase sequence and restriction sites, the vector also contains resistance genes against antibiotics. Thus, those that do not have the recombinant DNA molecule will be killed by antibiotics, allowing the transformed cells to flourish better. When the clone is needed for further analysis, it can easily be extracted out of the cell (U.S. Department of Energy Genome Program, 2009).
It is important to note that the mouse genetic material is very similar to that of humans. Thus, a known mouse G6Pase sequence can be used in hybridization as the heterologous probe in identifying the human G6Pase (McClean, 1997). How will this work? Briefly, human DNA sample will be treated with restriction enzymes to cut the long strands into smaller fragments. After doing so, the treated extract will be run through gel electrophoresis to separate the smaller fragments by weight. Then, using the mouse gene attached to a dye as heterologous probe, the strand which contains the human G6Pase will be detected and isolated. Copies of this isolated gene can be amplified through polymerase chain reaction (PCR). ...Download file to see next pagesRead More

Human gene
Such abnormalities often result in various genetic diseases. For instance, mutations in the gene, GALT, can lead to inherited autosomal recessive disorder called Classic Galactosemia or Galactose-1-phosphate uridyl transferase deficiency. A person with classic galactosemia is unable to metabolize galactose sugar into glucose in the liver and is susceptible to various diseases mostly of the liver and central nervous system (The New York Times).

Gene therapy
The genes thus introduced exert their benefits by either compensating for the abnormal genes or by producing beneficial protein or by supplementing the abnormal gene (Hecht, 2004). The first gene therapy clinical trial started in 1990 (Verma and Weitzman, 2005).

Gene Patenting
There are many benefits to gene patenting but there are also some controversies to its use. The United States Patent and Trademark Office (USPTO) regulates the patenting of genes and gene product (Barton, pg121-125). It has issued patents for a few gene fragments.

Gene Silencing
Characterization of such genes has evolved hope in the management of cancer. It has been proposed that detection of gene silencing in certain genes which are characteristic of tumors can help not only in early detection, but also may enhance the development of novel

Gene Expression
The contrast between the openness of euchromantin and the compactness of the heterochromatic implied that the euchromatic is the location of most gene function and led to the neglect of heterochromatin.

Gene therapy
This process is termed gene therapy. The field of gene therapy has been researched for decades and is continually being developed. Almost all diseases have a genetic component and by correcting the genetic code, the rules of the game can be changed. Though scientists are still figuring out the intricacies of gene therapy, and there is much room left for improvement, once gene therapy is mastered it could revolutionize the world by saving or increasing the quality of many lives.
