Das ist Ihre Geschichte, und nur AncestryDNA kann sie Ihnen erzählen.

With a mass of DNA of 1. The mass of DNA present in each of the cells is dependant on how complex the organism is, the higher the complexity the more DNA that is needed for the organism to function with its internal functions.

From the tables provided the mass of the DNA found in sperm cells can be noted. Sample Research Papers Deoxyribonucleic acid is present in all organisms. This can be explained by the fact that when an egg is fertilized by a sperm cell, the fertilized egg eventually becomes the starting point for all the different cells.

Also, because the organism has a DNA mass in each cell then DNA would have to be passed from the parents onto their offspring. Whether it is mammal, bird or bacteria DNA is responsible for a functioning organism. Since there is more information for the organism itself, then the DNA mass will increase.

More complex organisms have a higher DNA mass content per cell. This can be explained by the fact that the sperm cell is a haploid cell, and that it carries half the DNA that an organism will eventually obtain, the other half coming from the egg.

Looking at the two tables provided, there are some noticeable trends that could be identified, as well as conclusions that can be derived. The fact that all of the organisms, whether it is mammal, bird or fungi have a mass of DNA present in their cells shows that DNA is present for a reason.

The small but notable variance in the value of masses of the somatic cells can be attributed to experimental error. This value fits in with the rest of the values observed in the second chart.

The idea that more complex organism have more DNA mass per cell, that the mass of DNA in somatic cells is constant there is a range but it is very slight for any particular organism, that sperm cells are haploid cells and that all organisms have DNA present in their cells are ideas present from the tables provided.

If the sperm cell, with a DNA mass of 1. During the process of mitosis, the fertilized egg is duplicating to form a cluster of cells, while doing so the DNA is also being duplicated and eventually these cluster of cells will become specialized for different functions in different areas of the body.

From these four points extracted from the tables DNA seems to be an important component for each organism responsible for carrying information.

It can be noted that DNA is passed on from both the sperm and egg cell. The DNA mass found in a heart cell of the chicken measured at 2. If a mammal has an approximate DNA mass in each cell of 6pg and birds have an average DNA mass of 2pg per cell then this DNA has to have a specific function in the body, which explains its initial appearance in each cell.

The masses of DNA in the somatic cells of the chicken are all approximately the same.Read this essay on Dna Testing. Come browse our large digital warehouse of free sample essays. Get the knowledge you need in order to pass your classes and more.

Only at". Aug 24,  · The information provided with DNA tests has also helped wrongfully incarcerated people like Gary Dotson and Dennis Halstead reclaim their freedom. Related Topics:. DNA Evidence DNA testing has overthrown the way police collect evidence in a number of criminal cases, especially rape and murder and consequently had a large impact on many past cases.

However there are many disadvantages to DNA testing, such as a challenge of accuracy, the costs of DNA testing and the possible misuse of DNA.
