Previously relegated to servant tasks under the master DNA molecules, ribonucleic acids continue to surprise scientists.
Orphan genes — genes that are present in only one species, or a group of closely related species — are of particular interest to advocates of intelligent design.
The nucleus is a beehive of activity, where information is not just stored but processed, protected, transcribed, and duplicated by highly complex machines.
Why not treat the whole genome as functional? This is a radical concept, but perhaps the focus on genes distorts our understanding.
A clever method of RNA editing may explain the role of introns embedded in genes, and points to even higher levels of programming.
