Re: [math-fun] Junk DNA allegedly isn't. Big change in standard picture of life.

You've never heard of "loop-unrolling" ?? :-) It is conceivable that these stretches might act as some sort of "spacers", whose size/number might be more important than their content. One of the articles about this DNA map also indicated that portions of DNA that are far from one another in the linear sequence may end up near to one another when the DNA is in its normal folded state. Changes in the size/number of such stretches might mess up this folded alignment. At 07:08 PM 9/6/2012, rcs@xmission.com wrote:

A noticeable fraction (at least a few percent) of our DNA consists of many repetitions of short stretches of 6-25 letters. One might be excused for suspecting it had no important information.
