background: the homologous recombination (hr) is one of the conventional cloning methods for the production of recombinant dna. it is a quick method for in vivo dna cloning without using the high cost restriction enzymes. a few modifications in the cloning procedure can increase the efficiency of this method. m aterials and methods: in this study, effect of heating on the rate of the igg1 heavy...
In this paper, the author aims to study orthodox and protestant points of views on human cloning and investigate on their arguments for and against it. Both ideologies have abolished both reproductive and therapeutic cloning and put forward an argument against them. The only liberal view which allows therapeutic cloning, but refrains from explicitly commenting on reproductive cloning, is a cult...
It is well known that it impossible to clone an arbitrary quantum state. However, this inability does not lead directly no-cloning of coherence. Here, we show the coherence state which a stronger statement than 'no-cloning state'. In particular, with ancillary system as machine state, states whose greater on transformations are defined. Also, characterize class for cloning will be possible give...
Recent advances in cloning have offered hopes for disease treatment and resolving some other difficulties related to health, but this technology comes with social, legal, ethical, religious and other questions, and has caused different reactions worldwide. While some countries have enacted legislations on cloning, other countries have no clear law. Many countries and organizations, for various ...
A rapid DNA cloning system is a research interest of many scientists. TA cloning is one of the methods used for the cloning of PCR-amplified DNA molecules. The TA cloning method is a convenient and labor-saving replacement to traditional, restriction enzyme-mediated cloning strategies. A T-vector called pBlueskript ΙΙ SK-1 with the lethal gene ccdB was designed to construct a positive selection...
Human Cloning phenomenon that is accounted as one of the challenges of the present century is concentrated by legal community of most of the countries. One of the prior countries that reacted against this new phenomenon and took actions in legalization is America. Considering this country’s legal system, in the present article it is tried to explain legal condition of human Cloning in the...
Introduction: Cloning technology has been strengthened a long human desire for eternal life. The possibility of human cloning is the new challenges in medical education and medical ethics. The present study discussed the different perspectives in this field. Methods: This study is a review article. Related books and some database such as SID, Irandoc, Elsevier, PubMed, Magiran were searched us...
We investigate the role of symmetric quantum cloning machines (QCMs) in quantifying mutual incompatibility observables. Specifically, we identify a cloning-based measure whereby set observables maybe quantified terms how well uniform ensemble their eigenstates can be cloned via QCM. show that this new $\mathcal{Q}_{c}$ is {\it faithful} since it vanishes only for commuting prove an upper bound ...
We consider the problem of determining achievable region parameters for universal $1 \to 2$ asymmetric quantum cloning. Measuring cloning performance with figure merit singlet fraction, we show that physical is a union ellipses in plane. Equivalently, characterize parameter state compatibility two possibly different isotropic states, considering, first time, negative fractions.
In 1997, there was a report in Nature that announced the birth of Dolly the first cloned mammal in the world using nuclear transfer. After it, a lot of ethical and religious reactions were claimed against human cloning while no absolute opposition was presented against animal cloning. European :union: (EUROPA) as one of the most important and effective international organizations, has been play...
