We've come a long way since randy, and now for the first time we've demonstrated sex reversal after changing a non-coding region of dna rather than a protein-coding gene, explains professor robin-lovell badge, senior author of the paper. “this concept of ‘junk dna’ is really not accurate it is an outdated metaphor,” said richard myers of the hudsonalpha institute for biotechnology in alabama. Non-coding dna is just what it says it's non-coding dna you can think of the genome as being split up into two parts there's the stuff that codes for proteins. Moving away from the controversy over “junk” / non-coding dna, a very interesting piece of research was published recently the research paper, which has the title, origin and spread of de novo genes in drosophila melanogaster populations, was published on the science website on january 23, 2014.
No less a molecular luminary than francis crick, co-discoverer of dna’s double-helical structure, suspected it was “little better than junk” the phrase “junk dna” has haunted human genetics ever since.

The origin of the term “junk dna”: a historical whodunnit as textbooks would have it, the term “junk dna” was coined in 1972 by susumu ohno as part of his work on the role of gene and genome duplication.

In a paper published in genome research on nov 4, scientists at the genome institute of singapore (gis) report that what was previously believed to be junk dna is one of the important ingredients distinguishing humans from other species. Some noncoding dna is transcribed into functional non-coding rna molecules (eg transfer rna, ribosomal rna, and regulatory rnas) other functions of noncoding dna include the transcriptional and translational regulation of protein-coding sequences, scaffold attachment regions, origins of dna replication, centromeres and telomeres.

Technology networks is an internationally recognised publisher that provides access to the latest scientific news, products, research, videos and posters. Long stretches of dna previously dismissed as junk are in fact crucial to the way our genome works, an international team of researchers said on wednesday it is the most significant shift in scientists' understanding of the way our dna operates since the sequencing of the human genome in 2000, when it was discovered that our bodies are built and controlled by far fewer genes than expected.
In these two two-cell mouse embryos, the surface of the embryos is outlined in orange, the dna in the nucleus is indicated in blue and the activity of the line-1 gene is indicated via bright red spots one of the enduring mysteries of biology is why so much of the dna in our chromosomes appears to be simply junk. Today, new york times reporter gina kolata reported that “reanimated ‘junk’ dna is found to cause disease”  the research paper in question  does not refer (in so many words) to “junk dna,” for this term no longer is in vogue among geneticists but the paper does identify the role . According to wikipedia junk dna “is a collective label for the portions of the dna sequence of a chromosome or a genome for which no function has yet been identified” this however does not mean that all “junk dna” has a “function” although such dna can serve, as in the case of the anti-freeze example, as a source for novel functions.
