….Discoveries So Far.

"Unraveling the mystery of Dark DNA gives unique insight into unanswered questions about animals and change our current understanding of evolution.

The name likens it to dark matter, which is said to comprise 25% of the universe, yet so far remains elusive. In evolutionary biology, researchers can look at the genomes of species, see which genes cross over, and begin to decipher what function each serves…."

It assumes that DNA is 100% efficient, with no waste. All is accounted for.

John, that's not really what the article is saying or implying. There are missing genes in some species that cannot be "missing" for the animal to survive. Here's a better explanation:

They may just be better hidden as they are rich in guanine and cytosine sequences. Hence the "dark" analogy.

"Polymerase chain reaction (PCR) based cloning of gene of interest with high GC content is a long recognized problem. PCR is a most sensitive tool and various factors have to be optimized for amplification of gene of interest."
