Are you reffering to introns? Or gene regulators in bacteria operons?
"As a biologist, I firmly believe that when you're dead, you're dead. Except for what you live behind in history. That's the only afterlife" - J. Craig Venter
The only ones I know are introns. Non-coding sequences I think are the strand of Introns together after fragments of introns have been separated from the exons. I rad about in New Scientist awhile ago that the introns actually might have a function. I don't clearly remember what this time, but I will try to find it.

They are the non-coding part which is removed before translation. They are between exons, the coding parts.

Ok...I think I know them but get confused because of those glossary...
can you explain to me what are intron, exon, etc???
Q: Why are chemists great for solving problems?
A: They have all the solutions.
Introns- INtervening sequences. Thats how I always keep the bloody things defined in my all to addled brain. Its important to note that defining introns and exons are protein specific. Frame shifting or alternate initiation sites may change what is an intron and what is an exon. And yes, I'm still here.

an example of a function of intron sequences is..the retrotrasposons(LINES,SINES..)..am I completely wrong?they should have among others the capability to autocleave themselves and transfer and integrate in another site.
*Yeah, pretty much like all the members have said: Introns are non-coding DNA in the chromosomes. Their main role is as a Structural support to keep the DNA phsyically stabilized--sorta like scaffolding. You use it to support you while cleaning your gutter or painting your home. Introns are structural stabilizers; Exons are coding regions that direct the formation of physiologically important proteins.
Behold God's handiwork--it is in the biological universe and in your Mind. Praise Him!
