DNA or RNA) and they do not have cells. It is a particle much smaller than a bacterial cell, viruses enter the host cells and kidnap the enzymes and materials of these host cells to produce more copies of themselves, as the US author explains, they do not reproduce alone, to do so They use the genetic information of the cell they invade, inject their genetic material and multiply generating the death of the cell. Developing Viruses can attack from human beings to bacteria, but not all cause effect on systems of all species, since each virus can only infect one or a few of these. Some of these may be influenza or HIV. Each virus is different and because of that, its form of infection varies. Some...

DNA. This can also cause serious health problems, including cancer. Radiation is used in various ways such as, for example, medicine, industry, agriculture, teaching, research, art, .. In the field of medicine, which is the most important application for human life, ionizing radiation is used that are framed in the application of radiodiagnosis, radiotherapy and nuclear medicine techniques. Radiodiagnosis includes the set of visualization and exploration procedures of human anatomy through images and maps. Radiotherapy allows to destroy tumor cells and tissues by applying high radiation doses. Nuclear medicine is a medical specialty that includes the use of radioactive material in a non...

DNA begins to condense, then the metaphase comes where the two chromatids United SistersMititic spindle, anaphase begins with the breakage of connections between sister chromatids at the centromere. The appropriate material for your observation is the meristematic tissue of the roots of the onion. Introduction According to Carola d., (1995) mentions that the cell cycle is the universal mechanism for reproduction of eukaryot cells whose main event is the reproduction and duplication of the number of chromosomes, the myitosis being the division mechanism of the chromosomes, the nucleus and the entire cell. During the mitosis, the destruction of the nuclear membrane and the formation of the acromatic...

DNA propeller is packaged by protein in a condensed structure called chromatin. This allows very long DNA molecules to be in the cell core. Chromosomes must be replicated, divided and successfully passed to their daughter cells to ensure genetic diversity and survival of their offspring. Human beings have multiple large linear chromosomes contained in the cell core. Each chromosome has a centromere, with one or two arms projecting from it. Difference between human and bacterial cells Human cells differ from bacterial cells in a variety of ways. Bacterial cells usually have cell walls, while human cells do not. Most bacteria have only one circular chromosome;Human cells have chromosomes pairs that...

DNA. conclusion We have the economic limit, which is one of the most limiting, since, for example, we have sufficient knowledge to create a levitation train through the effect of superconductors at very low temperatures, but we are not able to make it come true, andthat the cost in liquid nitrogen and rare earth would be too high to...

DNA of a cell or an organism to change its characteristics, cutting in the precise place in which the modification is to be made and extracting a sequence; or, inserting a different one in its place. Despite the great controversy that brings to the speaking of this issue, the genetic edition can improve our quality of life and is exciting, but it does not lack risks or ethical implications. Next, there will. Also, when embryos are modified, unnecessarily, they may suffer damage and then be reflected in their offspring or even designing babies to our liking implies that genetic edition generates controversies in society. Although experiments can be continued, of course not in humans, so that the...

DNA, so that this event happens, certain activants are needed and quite ATP.On the other hand there is a stable phase where its next division is targeted. The interface seeks the increase in proteins and genetic material to get ready for the division of the hereditary material and begins in this same one and will be found in a unargured way in the cell, while in the process of division of the nucleusCell, for example, mythosis will be in charge of the chromatic. This process is regulated by factors such as proteins which can be internal and external such as cyclic.On the other hand, in the control sites, inhibitors and suppressors are presented, which detect and verify if the DNA is being handled...

DNA as well as chromosomal proteins, histones. However, there is still no cell division. During G2 everything has to be ready to go into division. It is precedent by a period in which the cell cycle control mechanisms ensure that DNA duplication has been carried out correctly. The synthesis of RNA and proteins continues and the nuclear membrane begins to be destabilized and a structure called acromatic spindle is forming.  At this time the cell is already ready to move on to the next stage: Phase M Source: It is.Slideshare.Net Cell cycle: Phase M, as we were saying, m is the stage in which the cell division itself is produced. It can be mitosis, if it gives rise to two daughter cells equal to the...

DNA), replicates it and transcribes RNA. Cytoplasm: It is the internal medium of the cell has the material that is within the cell especially ribosomes, also as water, salts and organic molecules. Cell membrane: it is a cell protection regulates the substances that enter and leave it, it also obtains nutrients and eliminates waste. (Audesirk, Audesirk, & Bruce, 2003)   Functional characteristics of cells Nutrition: The cells feed on organic matter, that is, they take energy that are found on the outside of the cell and make it nutrients in order to fulfill each of its functions and these in turn the metabolism that is very importantin each living being. Growth: Cells are divided into...

DNA replication process, it is when they begin to be cancerous, it is here when the cell begins to divide without some correct external signal, and they also stop displaying the inhibitionby contact and this part is when the cell begins to replicate in an uncontrolled way. Consequently, genes called "proto-oncogenes" begin to have problems, these genes are responsible for directing the normal growth of a normal cell, and when this damage occurs in these genes, the "oncogenes" occur, a mutation of theDamaged proto-awakens.  In the stage in which the genes that regulate cell growth and production are damaged and cells continue to multiply without control, a “neoplasm” occurs,...
