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...

A variety of methods have been developed for cloning PCR products, including blunt-end cloning (1), restriction cut back (2), ligation-independent cloning (3), uracil DNA–glycosylase (UDG) treatment of uracil-containing deoxyoligonucleotide primers (4,5) and TA cloning (6–8). Blunt-end cloning of PCR products often requires treatment of PCR products to polish the ends (9). Even with treatments,...

introduction bovine ephemeral fever (bef) is an arthropod-borne viral disease of cattle and water buffalo, spanning tropical and subtropical zones in asia, australia, and africa continents. the clinical signs of bef disease in cattle are acute febrile reaction, stiffness, lameness, depression, cessation of rumination, and constipation. this disease was caused by ephemerovirus of the rhabdovirid...

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...

RNAi mechanism plays a major role in silencing the expression of target genes by siRNAs. In the current study, in silico properties of 30 genes in omega-2 gliadin and 266 nt and 326 nt mutations were investigated before and after cloning in an expression vector. Specific primers were designed for 30 genes with spacer regions of 75 nt and 178 nt (for gene invert repeats). The frequency of siRNA ...

Cloning allows the asexual reproduction of selected individuals such that the offspring have an essentially identical nuclear genome. Cloning by nuclear transfer thus far has been reported only with freshly isolated cells and cells from primary cultures. We previously reported a method of cloning mice from adult somatic cells after nuclear transfer by microinjection. Here, we apply this method ...

In the random graph G(n, p) with pn bounded, the degrees of the vertices are almost i.i.d Poisson random variables with mean λ := p(n − 1). Motivated by this fact, we introduce the Poisson cloning model GPC(n, p) for random graphs in which the degrees are i.i.d Poisson random variables with mean λ. Then, we first establish a theorem that shows the new model is equivalent to the classical model ...
