With the exception of RecBCD and SbcB, Buchnera strains lack all of the known E. coli, replication forks frequently encounter Buchnera and Blochmannia: RecBCD and SbcB In many instances, recombination serves as a means of reinitiating DNA replication close to the site of the original injury. Whether problems affect one or both strands of the template determines which enzymes can gain access and ultimately the products generated.

To outline the recombinational pathways potentially available to bacterial mutualists it is necessary to summarize the functions available in the E. This ubiquity was called into question when the genome DNA replication and repair in the absence of recombination Until relatively recently, it was assumed that all cells employed RecA-like recombinases to solve intractable replication and repair problems requiring information transfer from an undamaged template 1, 2. Exchanging polynucleotide chains is vital for generating diversity and maintaining genomic integrity. Section snippets Mutualistic bacteria without RecA recombinaseĪll free-living organisms carry RecA family recombination systems responsible for finding and swapping homologous stretches of DNA. The possibility that specific defects in recombination encourage radical genome erosion in mutualistic endosymbionts and other intracellular bacteria is discussed. Depending on which functions remain, several different options are plausible. This question is addressed here by speculating on how the current repertoire of recombinases in symbiotic bacteria could enable recovery from potentially lethal injuries to the DNA template. Although debate has centred on the absence of selected recombination functions and their impact on a fixed genomic architecture, no explanation has been offered for how bacteria survive the loss of such an integral DNA repair system. The apparent inability of these bacteria to commence the recombinational exchange process seems to confer genetic stability by preventing any further rearrangements or lateral transfer events. One of the few exceptions to this orthodoxy is a group of γ-proteobacteria flourishing in obligate intracellular symbiosis with insects and deep-sea clams. My heart goes out to you all.Almost all cellular organisms employ RecA orthologues to guide the strand invasion reactions necessary for DNA recombination and repair. LIFE IS SO CRAZY! I could write my feelings forever but to everyone who has lost someone very dear all we can do is hold on to what we have left and take one day at a time. That was older sister's only child and I feel for her so much as bad as it hurts me to loose him as my nephew, but for her to loose a child my heart is forever wounded by these lost that we have endured. My nephew whom was like my little brother who I loved so much he was only five years younger than me was shot and killed five weeks after we buried my mother. Autopsy shows she had blockage, but no one knew she had anything going on because she looked and acted fine. I really do not want to get to much into detail but my mother passed in her sleep very unexpectedly. sometimes I wonder if I will ever be the same, I feel so empty without my mommy. This has been and still is a very trying time for my family and I. I lost my mother and nephew within five weeks apart in 2010. They have a very hard road ahead of them and I know it has to be tearing them up inside.

And if it were me I don't think that I could carry on. I feel that there pain must be unbearable. But my nephews and niece lost their mother and father. When I am down and hurting I always remember that I lost a sister. I can not image what they are going through. The reason I am here and typing is my sister and her husband had 5 children. They will be in my heart forever along with the pain that I don't think will ever go away.

I was still hurting from my pops death and I lose my sister.

A drunk driver hit and killed them on Memorial Day 05-28-2012. Nine months later I lost my only sister and brother in law in a Motorcycle accident.

I lost my dad last year on my birthday 08-25-65.
