c-value

My point is that both the amount of repetitive DNA sequences and the c-value itself correlate very strongly with a very simple physical variable, that this fact has been known for decades, and that any discussion of "junk" DNA and whether or not it has a "function" is basically worthless without this being explicitly discussed (this includes science journalists, ID guys, and much of Shapiro's stuff).

It has been known for a long time that the repetitive DNA sequences make up the majority in difference in c-value (c-value = amount of DNA per cell).

There are many reasons for the view, but for the most part it was a response to the observation that genome size shows no significant relationship with organismal complexity: The so-called c-value paradox:

Finally, and most importantly, it still leaves them facing the daunting task of explaining away the currently overwhelming evidence from the c-value paradox, to the existence of large deletion polymorphisms, to the phylogenetic evidence for neutral “drift” of most stretches of intergenic sequence, etc that much of genomic DNA in many eukaryotes has no phenotypic effect.

Mike Gene scores 2 points … c-value correlates extremely strongly with cell volume and nuclear volume — a massive, systematic correlation, across all eukaryotes, over five orders of magnitude of variation.

There is some very fundamental relationship in the eukaryotic cell between c-value and cell size.

The key to the puzzle of widely varying DNA amounts in organisms the “c-value” is that c-value correlates quite tightly with cell volume.

(Ambystoma mexicanum: c-value = 32 x 109 bp) were isolated and sequenced to characterize the structure of genic regions.
