In probably every textbook illustration you can find on human chromosome structure, there is always the same recurring theme: They are depicted as simple, linear strands of DNA wound up much like garden hoses or balls of twine.  However, you … Continue reading

Are cancers new species?

There is a very interesting article suggesting that cancers may actually be new species.  In this study, chromosomal probes specific for each chromosome in a human cell are matched against chromosomes found in human cancers.  In Figure 8 of this … Continue reading

Cellular differentiation and endosymbiosis revisited

In an earlier post on this page I discussed evidence that the eukaryotic nucleus is compartmentalized and how this compartmentalization may allow one compartment to become irreversibly differentiated through DNA rearrangements and deletions while leaving the remaining compartments untouched. I … Continue reading

Prison escape by cellular inmates?

What you see in the picture below looks like some kind of primitive fungal colony, releasing spores. In was in fact derived from a colony of serum-arrested mouse L-1210 cells degrading under a coverslip. The immediate reaction of a tissue … Continue reading
