Is cell mitosis composed of smaller cell mitoses?

Ok, this is a really weird title, even for me. However, this whole blog is about how our cells and DNA were stitched together using smaller endosymbiotic cells and their DNA. If these smaller cells also had mitotic spindles, they may have been integrated into the larger host spindle as well. If so, this means that our mitotic apparatus used to separate duplicated chromosomes is not a simple uniform organelle but has subcomponents to it from cellular endosymbionts. Far fetched? Well, studies have shown that the centrosome complex can break up into units resulting in more than two poles during mitosis. This is different from other studies where centrosomes have duplicated more than once, generating additional poles.

You may check out the centrosome models I have placed on this blog to get a better idea of how this might work.

About frankabernathy

I am a retired cell biologist and alumnus of Ohio State University. I became interested in chromosomes as far back as the 1960's when I wrote a term paper on the effects of radiomimetic drugs on chromosomes. I was fascinated at how they could break apart and reform new structures so easily. I became further involved in the early 1970's after taking a cytogenetics course at the University of Arkansas. I took that knowledge with me to Ohio State in 1980 where I eventually worked on my research and completed my Ph.D. dissertation, "Studies on Eukaryotic DNA Superstructure". My studies and later research suggested that the DNA within the eukaryotic chromosome is not the simple, linear molecular thread so widely suggested in all the classic textbooks published today. Instead, it may be the culmination of a geologically rapid set of endosymbiotic events where microorganisms plug into each other to create something greater than themselves.
