Well, the question is :
What is a normal gene ?
As far as I know, and this could be an excellent topic for
bionet.genome.gene-structure, there is nothing more complicated
that the interaction between: the gene, the flanking sequences,
the regulation sequences, the specific regulatory genes, and
the chromatin regulation.
If you try, one day, to model those interactions, you will
probably touch how evolution can be so continuous (not sure
it is the word) and not "jumpy".
Just have a look on recent publications about TIFs and HP1.
And other ones regarding chromatin. Perhaps Jerry could add
some references here ?
Well, not sure I have to add a followup-To because
it seems that some of you are using the mail2news bionet
