Samuel … Junk DNA is a synonym for nonfunctional DNA or DNA that has no relevant biological function. Most organisms have some junk DNA in their genomes - mostly pseudogenes and fragments of transposons and viruses - but it's possible that some organisms have substantial amounts of junk DNA. All protein-coding regions of genes are generally considered as functional elements in genomes. …
WebOnion Test. The onion test is a way of assessing the validity of an argument for a functional role for junk DNA.
