DNA. Mutations order the cells that grow and multiply fast, which creates a mass (tumor) of abnormal cells. Abnormal cells continue to live when other healthy cells die. They can invade nearby tissues and get rid of an initial tumor to spread other parts of the body (metastasis). RISK FACTOR'S The factors that can increase the risk of ovarian cancer are the following: Advanced age. Ovary cancer may appear at any age, but it is more frequent in women 50 to 60 years. Hereditary genetic mutations. A small percentage of ovarian cancer types is due to a genetic mutation that your parents inherit. The genes that are known to increase the risk of ovarian cancer are called "breast cancer gene...

DNA that enters and leaves the nucleosomic nucleus particle and has an important role in the establishment and maintenance of chromatin structures of higher order. Each H1 is made up of certain proteins related to different species. However, in eukaryotes they have the same structure (Izzo, Kamieniarz and Schneider, 2008). It is believed that there are several hierarchical levels of DNA packing in chromatin, from a 10 Nm chromatin fiber (lower level of chromatin) that is packaged in a 30 nm fiber. It is believed that the transitions between the fibers of 30 Nm and 10 Nm are essential for the control of the transcriptional state of the chromatin (Razin and Gavrilov, 2014). The most accepted model...
DNA test is not possible. Histology does not routinely distinguish between HSV-1, HSV-2 or the Varicela Zoster virus (VZV). The specific type serology can distinguish between HSV-1 and HSV-2 but cannot distinguish a primary infection from recurrent infection or differentiate oral genital HSV infection. The specific type serology is not used routinely for the treatment of genital infections by VHS, but it can be clinically useful if a patient wants to know if he is at risk of contracting VHS of a couple with a history of genital herpes. Serological tests aimed at anti-HSV immunoglobulins confirm a primary HSV infection and discard previous viral exposure. The acute and convalescent sera are obtained...
DNA. They are a group people who come from pre -Columbian cultures and that have various components that distinguish them from the rest of the population, in addition to their genetics, they include cultural differences totally different from the western. Indigenous peoples have existed from the beginning of humanity, were the first to deal with the earth and for that reason they should have their most insured rights than none of us. The problem is that their rights are not respected despite everything mentioned above. The regulation for the exploitation of natural resources in their territories, has had little or no regulation by the authorities, in addition to having a minimum representation in the...
DNA of a sick patient is studied, you can know where the affected genes are. But despite the advance of science, in recent decades, the knowledge of all human genes is not yet complete. The main objectives of the human genome project (HGP) that lasted 13 years, from 1990 to 2003, were to establish the DNA sequence, such as the location of 100.000 human genes. Human Genes List The scientists of that time believed that once they know the DNA sequence, this would help to determine quickly where all the genes were. But over the years this was verified that it was not so. There are currently several human gene databases in competition, with thousands of differences between them. Although a large number...

DNA bases either individual or a small group of base pairs. According to the structure and sequence of a gene, the shapes in mutations could change a wild type gene. Mutations that eliminate or decrease gene function are the most common. There are two types of specific mutational changes in DNA: Base substitutions: These are the mutations in which one pair of bases is replaced by another torque. Bases or delection: They are nucleotide pairs. The simplest of these mutations is the addition of simple base pairs. Hot points When observing a set of mutations induced by different mutagens, there is a different specificity that is characteristic of each mutagen, this specificity is a product...
DNA S Bullet Synthesis, M, Mitosis, and G1 and G2. In the S stage, the DNA of each semiconutative chromosome is replicated. There is a pair of sister chromatids when the chromosome is divided, and each chromatid contains a replicated DNA molecule. These chromatids can only be microscopically visualized in the mioposis stage. During the myitosis, the DNA daughters molecules separate the opposite poles of the daughter cell, and that is where two equal nuclei are formed in the daughter cells. Most eukaryotic organisms also reproduce sexually. The beginning of the sexual cell division is carried out with a diploid cell called meiocyte, these are a subpopulation of reserve cells for cell division....
DNA of an organism, this brings a specific purpose for the achievement of a specific objective that influences the modification of the genome and this leads to the characteristics of the embryo to change for the procedures that are carried out in turn are serious Consequences in a established period of time where science has not planned the duration caused by this behavior of embryo changes. Nowadays controversies have been generated regarding this issue, since each person has different points of view and opinions about genetic manipulation, from my position it should not experience genetic engineer, because mainly it brings serious consequences in which they havecaused the death of said organism....
