Chi (5'-GCTGGTGG) is a recombinator in RecA-RecBC-mediated recombination in Escherichia coli. In bacteriophage lambda vegetative recombination, Chi is fully active only when it is correctly oriented with respect to cos, the site that defines the ends of the packaged chromosome. Here we demonstrate that packaging from cos is not necessary for this cos-Chi interaction. Our evidence suggests that ...

We consider the t-hook functions on partitions $$f_{a,t}: \mathcal {P}\rightarrow \mathbb {C}$$ defined by $$\begin{aligned} f_{a,t}(\lambda ):=t^{a-1} \sum _{h\in {H}_t(\lambda )}\frac{1}{h^a}, \end{aligned}$$ where $$\mathcal )$$ is multiset of partition hook numbers that are multiples t. The Bloch–Okounkov q-brackets $$\langle f_{a,t}\rangle _q$$ include Eichler integrals classical Eisenstei...

The singlet majoron model of seesaw neutrino mass is appended by one dark Majorana fermion $\chi$ with $L=2$ and complex scalar $\zeta$ $L=1$. This simple setup allows to obtain a small radiative anchored the same heavy right-handed neutrinos, whereas one-loop decay standard-model Higgs boson $\chi \chi + \bar{\chi} \bar{\chi}$ provides freeze-in mechanism for be light matter Universe.

Double-stranded cDNA was synthesized from a mouse liver mRNA fraction enriched for metallothionein mRNA activity, ligated to restriction site linkers, inserted into pBR322, and used to transform Escherichia coli chi 1776. The sequence of the largest plasmid containing DNA that hybridized to metallothionein mRNA was determined and shown to contain a 380-base-pair insert that includes the entire ...

Screening of an induced Ehrlich ascites cell-derived lambda gt11 cDNA library with an antibody (GP1), immunoreacting specifically with centrosomal antigen(s) of interphase and mitotic cells of different species, released a partial cDNA clone (lambda P10A) encoding the carboxy-terminal section of a centrosome-specific antigen. This specificity of the clone lambda P10A could be verified by lacZ-d...

Debnath and De La Sen introduced the notion of set valued interpolative Hardy-Rogers type contraction mappings on b-metric spaces proved that a complete space, whose all closed bounded subsets are compact, mapping has fixed point. This article presents generalizations above results by omitting assumption compact.

Chi (x, 5'-GCTGGTGG) is a recombinator in RecAand RecBC-mediated recombination in Escherichia coli. In vegetative recombination between two bacteriophage lambda strains, one with and the other without Chi (a+x+bX u-Xob+), the X-containing recombinant (a-X+b-) is less abundant than the nonx-containing recombinant (a+xob+). Previously this was taken was evidence for nonreciprocality of X-stimulat...
