Question

So far, dark DNA seems to be present in two very diverse and distinct types of animal. But it's still not clear how widespread it could be. Could all animals genomes contain dark DNA and, if not, what makes gerbils, birds and humans so unique?

Answer 1

The most energizing riddle to tackle will work out what impact dull DNA has had on creature development.

In the case of the sand rodent, the transformation hotspot may have made the creature's adjustment to betray life conceivably. In any case, then again, the transformation may have happened so rapidly that regular choice hasn't possessed the capacity to act quick enough to expel anything hindering in the DNA. Assuming genuine, this would imply that the unfavorable changes could keep the sand rodent from getting by outside its present desert condition.

This sort of dim DNA has recently been found in fowls. Researchers have discovered that 274 qualities are "missing" from right now sequenced winged creature genomes. These incorporate the quality for leptin (a hormone that controls vitality balance), which researchers have been notable find for a long time. Indeed, these qualities have a high GC content and their items are found in the fowls' body tissues, despite the fact that the qualities seem, by all accounts, to be absent from the genome successions.

The revelation of such an unusual wonder absolutely brings up issues about how genomes develop, and what could have been missed from existing genome sequencing ventures. Maybe we have to return and investigate.
