Humans have 23 pairs of chromosomes. Because human chromosomes in pairs?
Each pair of chromosomes is called. homologous chromosomes means that the same length and their centromeres are in the same situation that followed the same pattern of light and dark bands when displaying colors, and carry the genes of the same hereditary characteristics in line in the chromosome in the same order .
Among the 23 pairs of chromosomes, the male sex chromosomes, only because they are heterogeneous XY chromosomes, while females had a couple who are XX. Is the Y chromosome, which is of great importance to the genealogist, because, as one passes from father to son virtually unchanged, is a nickname for a signature or fingerprint that is sent in the same way in many cultures.
Now that you've learned something about human chromosomes, but chromosome not only documents containing DNA. Now, also known as mitochondrial DNA, which is essential for cell growth.
Mitochondria are small, ranging from 0.002 to 0.008 mm in length, where data can only be seen by electron microscopy. Mitochondria are the power in our cells to produce energy for the reaction and metabolism. Let me give an example in the role of mitochondria in human cells. When you eat carbohydrates, which break and finally converted into glucose. energy release from mitochondria of glucose to fuel cells.
Mitochondria contain a small amount of DNA used for the manufacture of thirteen of the proteins that are necessary for its business. Mutations in the coding region of the proteins in the mitochondrial DNA can cause a variety of diseases in humans, usually with neuromuscular dysfunction, or certain forms of diabetes.
Of interest to the genealogist (among others) is that all mitochondria come from a person of his mother. Although the sperm tail is full of energy for mitochondria his long journey to the tail of egg and sperm mitochondria in the design and not by the oocyte. That is why all mitochondria in the fertilized egg of the mother of one.
Each cell contains thousands of copies of mitochondrial DNA, but only a set of chromosomal DNA.
