I will praise thee; for I am fearfully and wonderfully made: Psalm 139:14
"Scientists at Caltech may have sounded the final death knell for the “junk DNA” myth.
A new picture begins to emerge of hierarchical organization in the nucleus. No longer does it look like spaghetti in a basketball.
On the contrary,
there are territories and compartments throughout the interior.
Caltech’s work adds to earlier knowledge of nuclear compartments:
Nucleolus: contains transcribed ribosomal RNAs and associated processing molecules.
Speckles: contain pre-mRNAs and splicing components
Transcriptional condensates: contain RNA polymerase II machines and factors.
*Now, additional hierarchical organization is being found in the nucleus. In the newly identified territories are found ncRNAs (noncoding RNAs, not destined for protein) — thousands of them — that are doing important jobs: guiding regulators into the right territories where “essential nuclear functions” need to take place."
