Ways of Extracting the DNA Molecule
DNA component is always present in each and every individual’s body. The component is formed from the fusion of the cells of the two parents who are responsible for the birth of the baby. There is no error formed in the formation of the DNA and it is usually used to determine the real parents of the child by extracting it. DNA extraction involves separation of the DNA molecule from the proteins, membranes and the other cellular materials in the cell. The exercise of extracting it might not be that easy and needs adequate time for the accurate results to be found.
The whole extraction process is very sensitive since any contaminations might be a problem and will prevent the real results from being achieved. Methods of extracting it are three and the most suitable one can be used, the incubation method has to be done overnight, the reagent one which is newly installed and there is the protocol type which is the easiest method completed in just some few minutes. There are situations that can only restrict the use of a certain method depending with the current conditions and the people involved will have to follow them.
Identification of the DNA molecule has been made important by the many factors that are available in the molecules and can be identified with them. DNA molecules are negatively charged and it becomes easy when testing of the charges is done since any negative molecule is automatically the one. The DNA molecule is made up of the many chromosomes that are coiled and this makes up the structure of them and since they are negatively charged and the proteins are usually positively charged which makes them attract to each other.
DNA extraction has many processes involved in it and they all have to be followed for the perfect results to be attained. The whole cell membrane has to be raptured for the components to be released and separated for each and every component to be on its own. It is a bit difficult for the whole membrane to be dealt with if it is in its initial state because the components have to be extracted. The best way to open the cell membrane without problems is using heat or detergents to smoothen it.
Then by using the DNA features, one can separate it from the other many components in the cell. The features have to be looked into carefully to avoid confusion since there might be other components having the same features and all have to be used carefully. Isolation is the final step made if the DNA molecule has been extracted for the wanted use.
