Abstract No-cloning theorem forbids perfect cloning of an unknown quantum state. A universal machine (UQCM), capable producing two copies any input qubit with the optimal fidelity, is fundamental interest and has applications in information processing. This enabled by delicately tailored nonclassical correlations between copying qubits, which distinguish UQCM from a classical counterpart, but w...
As a scientific achievement of the modern world, cloning has caused both fears and hopes for the future of the humankind. It is categorized into human and non-human cloning, each of which are subdivided into therapeutic and reproductive subtypes. Of these subtypes, only the reproductive category has produced much controversy, but there is not much debate on animal cloning. Human cloning for the...
Human cloning is one of the most controversial issues in ethics. This paper, with analytic-descriptive method, deals with Kant;aposs principle of ends and permission or prohibition of human cloning from its point of view. According to Kant;aposs principle of ends, any action in which humanity is taken as a means, not as an end, is prohibited. There are different interpretations of taking humani...
Background Despite successful cloning of many mammalian species, the cloning efficiency is extremely low compared to that of IVF raising the possibility of the existence of epigenetic barrier preventing successful cloning. MaterialsAndMethods Using comparative transcriptome analysis comparing transcriptomes of IVF and SCNT embryos and that of donor cells, we identified epigenetic barrier and fi...
A method is described for cutting DNA at specific sites that are 8 and 10 base pairs long. The DNA is first treated with a specific methylase, either the restriction-modification enzyme M. Taq I, which converts the 4-base sequence T-C-G-A to T-C-G-mA, or the similar enzyme M. Cla I, which converts the 6-base sequence A-T-C-G-A-T to A-T-C-G-mA-T. The DNA is then cleaved with Dpn I, a restriction...
The activation of maturation-promoting factor (MPF) is required for G(2)/M progression in eukaryotic cells. Xenopus oocytes are arrested in G(2) and are induced to enter M phase of meiosis by progesterone stimulation. This process is known as meiotic maturation and requires the translation of specific maternal mRNAs stored in the oocytes. We have used an expression cloning strategy to functiona...
Cloning, as a new technology, has attracted the attention of statesmen, physicians, lawyers and other scientific communities. This phenomenon both opens a new horizon on human society regarding its therapeutic features and brings some concerns to it. This technology is divided into two parts: Human or generative cloning and therapeutic or investigative cloning. The first meaning which comes to ...
BACKGROUND The identification of protein trafficking signals, and their interacting mechanisms, is a fundamental objective of modern biology. Unfortunately, the analysis of trafficking signals is complicated by their topography, hierarchical nature and regulation. Powerful strategies to test candidate motifs include their ability to direct simpler reporter proteins, to which they are fused, to ...
