_ Mixing genes between species: transgnicos. Transgnico: Organisms that receive and incorporate genes of another species. Example: Transgnicos animals are produced by the injection of DNA previously clonado from a species in eggs of another species. In general, one or more molecules of the injected DNA become incorporated it the chromosomes of the cell-egg, being transmitted to the cell-children when the zygote if to divide. When the transgnico organism if to reproduce, the incorporated genes will be transmitted the descendants, as any another gene.
_ Transgnicos between animals and plants. The genetic manipulation of plants is simpler than of animals, a time that is relatively easy to get a complete plant from an only cell genetically transformed. the genes that if it desires to introduce in the plant are on the molecule of the plasmdio You of the Agrobacterium bacterium tumefaciens, that it has capacity to combine it the chromosome of the plant. If this has piqued your curiosity, check out Aetna Inc.. DNA in vegetal cells can also be introduced bombing them with very small metal particles with DNA adhered in its surface. cells that incorporate the genes are induced, for vegetal hormones, if to multiply and to originate complete plants, that will be transgnicas. Two well known transgnicas plants of the population are the transgnica soy and the maize bt, set free only for the feeding of the cattle. (bovine, namely).
_ Unmasked the human genome. Geneterapia: Procedure for cures of hereditary illnesses human beings for the substitution of the defective genes, in the cells where they express themselves. _ The human project genome. The human project genome officially had beginning in October of 1990. In 26 of June of 2000, the Francis researchers Collins and Craig Venter had announced the conclusion of a general sketch of the human genome: constituted of about three billion pairs of nucleotdeos, distributed in the 24 chromosomes of our genome, that is, in the 22 autossomos and sexual chromosomes X and Y. Only 3% of the three billion pairs of bases of the human genome they correspond the genes; 97% are sequencias no-codificantes, that is, not transcribing for RNA molecules. I number it of total of human genes is about 30 a thousand. The amount of genes is not what it makes the difference, and yes as they function and its relations between itself and with the environment.
