A thick piece of chromosome sitting next to another thick piece with a thin central element line connecting the two. These synaptonemal complex should form during meiosis the entire set of the entire set of chromosomes in normal plant cells, but Ma found that it does not form in the germ cells of the mutant plant. You only see a lot of thick pieces that did not get paired with another piece because RAD51 is not there to bring the two parts together, says Ma. The electron micrographs show definitively that the RAD51 gene in plants for the formation of the required key element that couples the two chromosomes.
The researchers microscopic images of meiosis in its showed were not neat chromosome packages but a chaos of many broken sections of chromosomes. ‘We found that plants in which the RAD51 gene unable unable to be broken parts of their chromosomes recombine during meiosis ‘. Researchers. Researchers additionally this finding tested by introducing into the plant a mutation in a gene called SPO-11, which deactivates the protein that intersects chromosomes. ‘in plants in both in both ER-11 and RAD51, we find intact chromosomes, not the jumble of chromosome fragments, ‘Ma reports. ‘Because the chromosomes are not cut in the first place, you do not really need the RAD51 to repair it.The survey found:. Broadcasting coverage reported dual programs of the following trial:.. Ninety-four % of the physicians who relations with the pharmaceutical companies, where the companies will provide you with food and drink, pharmaceuticals samples and other gifts and payment, according to a study on the Thursday in a New England Journal of Medicine, the Pittsburgh Post – Gazette reports released. For the study, at Harvard Medical School scientists the end of 2003 and early 2004, Polls View and an $ sent 20 on select a random sample of 3,167 anesthetist, cardiologists, GPs, surgeons, internists and Dentists Paediatricians (Ruby, USA Today, partially more than 1,600 doctor the survey.
