As far as I know, the telomerase is the important part of the Chromosome.The telomerase contains RNA and it protects the Chromosome from being cut.

As far as I know, the telomerase is active only in embryonic or some cancer cells, but definitely not in somatic cells.

Cis or trans? That's what matters.

i agree with ChinnRod

Telomerase is not active in normal cell.But it exist.

BY the way ,some people tell me it is mrna.

yeah, but as it's not expressed, it's obviously not on chromosomes, right? :wink:

You see, how simple :lol: But I would say pre-mRNA, because it's further proccessed till it becomes mature mRNA

I know theres portion of human DNA in chromosome, but I do not know much about hnRNA, im sure it contain in nucleus, but I cannot recall if its from choromosomes.

One of my favorite RNA genes that then binds to the chromosome: Xist
http://en.wikipedia.org/wiki/Xist
its role is to silence the one X chromosome in the double XX cell (female)
