A: There are three main reasons for concern. First, efforts to produce cloned human embryos require large numbers of women's eggs. In order to retrieve eggs, researchers give women hormonal treatments to first "shut down" and then "hyper-stimulate" their ovaries, followed by surgical extraction of multiple eggs. This is a time-consuming and invasive process associated with potentially serious health problems. Second, research cloning raises concerns because of the exaggerated and probably unrealistic claims of "personalized" therapies made by many scientists and advocates.
If the many technical obstacles to such treatments were ever overcome, they would likely be enormously expensive, and thus inaccessible to most people. Finally, because research cloning involves the same technique that would be the first step in reproductive cloning, effective oversight to prevent efforts to produce cloned humans would be required.
Concerns about unauthorized efforts to clone a human being are heightened by the fact that laws against reproductive cloning have not yet been passed in many jurisdictions.

A: Research cloning is legal in most jurisdictions. A few US states prohibit it, but others actively encourage and fund it. At the federal level, the US government will not at present fund research cloning, nor does it provide regulation or oversight of research cloning efforts. Gallup released its annual Values and Beliefs survey on June 4th. This is the 18th year in which Gallup has conducted its poll about the moral acceptability of various topics, including human cloning, animal cloning, and since medical research using stem cells obtained from human embryos.
CGS has been keeping track of public opinion studies, especially on inheritable genetic modification and human cloning , as well as animal and pet cloning , with some data going back as far If sci-fi writers of the past somehow visited us today, they might wonder: where are all the clones? As recently as the year , it seemed almost inevitable that rogue scientists would start human cloning any day.
Dolly the sheep Cloning is back in the headlines. Researchers managed to create two macaque monkeys by cloning, and immediately there was talk about using the Dolly-the-sheep technique to create human clones There has been a big scientific breakthrough that may bring the world one step closer to cloning humans. They represent the next big step Main navigation.

Save to Library. GroEL from the psychrophilic bacterium Pseudoalteromonas haloplanktis TAC molecular characterization and gene cloning. The heat shock response of the psychrophilic bacterium Pseudoalteromonas haloplanktis TAC PhTAC gives rise to the production of several inducible proteins. The data herein reported demonstrate that PhGroEL cold adaptation consists in a shift of the protein properties towa MYB-6 gene modulates the biosynthetic pathway of anthocyanins in plants in response to cold stress.
In the present study, the full length version of this gene was identified and characterized from black carrot Daucus carota L. The size of amplified MYB-6 gene was found to be bp which was confirmed through gene sequencing analysis. Elution and purification of MYB-6 gene was done successfully. Confirmation of successful transformation has revealed no growth of cells on Kanamycin enriched LB-plates, while as clear colonies were found on vector and vector-insert embedded LB-plates. Further, analysis via PCR, restriction digestion and gene sequencing has confirmed successful cloning of carrot derived MYB-6 gene in E.
In the current study, we aimed to create clone of MYB-6 gene that could act as easy to use gene pool candidate for amelioration of cold susceptible crops and for sustainable agricultural development through various high-throughput transgenic studies.

Betaine homocysteine methyltransferase: gene cloning and expression analysis in rat liver cirrhosis. Identification of conserved promoter elements for aldB and isozyme specific residues in aldolase B. The comparison of three complete aldolase B genes-including known and putative regulatory elements-is presented. The promoter sequence alignment included the nonmammalian chicken aldolase B gene and confirms the promoter sequence conservation of those elements where trans-factor binding has been.

In "Clon'd" I ask in what way the problem of the "clone," as it confronts us today, can be separated from modern and ancient questions concerning naming. Beginning with a philological analysis of the word "clone," I then turn to the Beginning with a philological analysis of the word "clone," I then turn to the conceptual parallels between vegetative reproduction and linguistic reproduction.
Through a comparison between the clone and the double, I argue, by way of conclusion, that the fear of the clone corresponds to a relatively new notion of genetic identity, which has repercussions far beyond the biotechnological realm.

Khachatourians and Daniel Khachatourians and Daniel Uribe protoplasts and hyphal bodies. The phylogenetic diversity of Thermus and Meiothermus from microbial mats of an Australian subsurface aquifer runoff channel. Spectral analysis of the cell free extracts of four mat samples colonizing a Great Artesian Bain GAB aquifer bore runoff channel suggested that Thermus was present in the 75 degrees C grey mat, Meiothermus was present in the 66 degrees Enumeration studies indicated that Thermus dominated the grey mats and Meiothermus dominated the red mat but both were absent in samples collected at the bore source 89 degrees C and below the bore source 88 degrees C.

Culture-dependent studies followed by 16S rRNA gene sequence analysis indicated that 13 of the 14 Thermus isolates clustered closely with each other and to T. The two Meiothermus isolates were closely related to Meiothermus ruber. A culture-independent study with 16S rRNA gene clones concurred that Thermus dominated the grey mat, but to a lesser extent in the red mat and the green mats and its complete absence in the brown mat.
Of the four Thermus phylogroups identified one phylogroup dominated the cloned library and was related to the cluster represented by T. The second most dominant phylogroup was related to the cluster represented by T. Meiothermus was only represented in the 16S rRNA gene libraries of the red, green and brown mats and formed two phylogroups, of which the most dominant was associated with the red mat and phylogenetically related to M.
