Latest ‘junk DNA’ discovery: Operating system for cells

In the August 1 issue of CELL, researchers from the Gene and Stem Cell Therapy Program at Sydney’s Centenary Institute revealed another function of introns, or noncoding nucleotide sequences, in DNA. They reported that gene-sequencing techniques and computer analysis allowed them to demonstrate how granulocytes use noncoding DNA to regulate the activity of a group of genes that determines the cells’ shape and function.

Their report adds to growing experimental support for the idea that all that extra stuff in the human genes, once referred to as “junk DNA,” is more than functionless, space-filling material that happens to make up nearly 98% of the genome.
