Much of the "junk" DNA in Drosophila shows signs of either negative or positive selection, according to a study in this week's Nature. An analysis by Peter Andolfatto of the University of California, ...

Introns are therefore non-coding DNA by definition, and are transcribed into the preliminary messenger RNA molecule, but are then removed to give rise to the mature form. They may play regulatory ...

These genes emerged from ancestrally non-coding DNA since D. melanogaster split from its close relative, D. simulans. The new genes showed evidence of being under selection, meaning that they were ...

Sorting through non-coding DNA to find the root of chemotherapy resistance "The non-coding 98% of the genome contains instructions," said co-first author Jackson Mobley, Ph.D., St. Jude Department ...

For many years, it was easier for scientists to simply ignore all of that extra genetic material, and it was written off as junk DNA that served no purpose. But in recent decades, the importance of ...

Currently, we don’t understand the meaning of most of the DNA. When it comes to understanding the non-coding regions of the DNA, it seems that we have only started to scratch the surface. This is ...

The mechanism reveals that damages to non-coding DNA, which are often hidden, accumulate more in slowly proliferating tissues ...

Before putting proteins together, DNA gets transcribed into threads of RNA that are chopped and reassembled into smaller pieces. During the chopping, the non-coding stretches — the junk — are ...

The human genome is made up of three billion letters of DNA and at each position it is possible ... “These parts of the genome are known as ‘non-coding’, but that doesn’t mean that they are not ...
