Inside the nucleus of a human cell, there are approximately two meters of DNA folded into a multi-layered 3D structure called chromatin, which allows all of our genetic information to be compacted into a tiny little space.

MIT biologists have discovered a mechanism that allows cells to read their own DNA in the correct direction and prevents them from copying most of the so-called "junk DNA" that makes up long stretches of our genome.

A team of researchers from Portugal, Israel, Poland and Spain has found the gene that prompts the parasite Trypanosoma brucei to change from its normal long, slender shape to one that is short and stumpy. In their paper published ...
(Phys.org)—Transposable elements—or transposons—are DNA sequences that move in the genome from one location to another. Discovered in the 1940s, for years they were thought to be unimportant and were called "junk DNA." ...

Over a decade after sequencing the human genome, it has now become clear that the genome is not mostly 'junk' as previously thought. In fact, the ENCODE project consortium of dozens of labs and petabytes of data have determined ...

Scientifically speaking, there is no bad DNA, though we like to blame it for unruly hair, klutziness or poor gardening skills. There is, however, junk DNA.
