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, ...

The team first challenged the model to create a full set of human mitochondrial DNA. With only 13 protein-coding genes and a handful of RNA types, these genomes are relatively small, but the resulting ...

Only around two percent of the human genome codes for proteins, and while those proteins carry out many important functions of the cell, the rest of the genome cannot be ignored. However, for decades ...

The human genome contains about 20,000 protein-coding genes, but that only accounts for roughly two percent of the genome. For many years, it was easier for scientists to simply ignore all of that ...

A recent study published in Nature Medicine found that mutations in non-coding DNA might underlie many cases of previously unexplained neurodevelopmental disorders.4 The mutations were found in a ...

It was once thought that non-coding regions were effectively “junk” DNA.1 Using very different technologies, two new studies have added further evidence to an already large pile showing that ...

Non-coding DNA variants contribute to acute lymphoblastic leukemia (ALL) chemotherapy resistance. St. Jude Children's Research Hospital scientists have identified specific DNA variants in the non ...

Non-coding DNA variants contribute to acute lymphoblastic leukemia (ALL) chemotherapy resistance. Explore new technology used in the St. Jude-led discovery.

Non-coding RNA is a ribonucleic acid molecule that is generated from the non-protein coding DNA sequence, that makes up 98-99% of the human genome. A plethora of different types of functional non ...

Butterfly wing patterns have a basic plan to them, which is manipulated by non-coding regulatory DNA to create the diversity of wings seen in different species, according to new research.

Non-coding DNA had previously been implicated in neurological conditions via several different mechanisms, but the role of strand breaks and their repair is a new finding. According to the study ...

The expression of ZNF558 itself is regulated by the size of a non-coding structural element in DNA called a VNTR, short for variable number tandem repeat that is longer in chimpanzees than in humans.
