Junk DNA

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.
junk DNA (jngk)
n.
DNA that does not code for proteins or their regulation but is thought to be involved in the evolution of new genes and in gene repair, and constitutes approximately 95 percent of the human genome.

Junk DNA
Any long stretch of non-protein-coding DNA that composes 97–98% of the human genome, which has been highly conserved in plant and animal genomes over millions of years. It is now recognised that non-coding DNA determines the differences in transcription rates of genes, which is what makes each of us unique, making junk DNA is a misnomer

The enzyme normally DNase1 eliminated the so-called junk DNA and other cellular debris by grinding it into small pieces for easy removal.
Byline: ANI Washington, Sep 22 (ANI): Researchers at the University of Edinburgh have discovered that a protein enables sections of so-called junk DNA to be cut and pasted within genetic code- a finding which could speed up the development of gene therapies.
In fact most of the apparently junk DNA is active, so it must be playing an important role.
