Researchers reveal an RNA modification influences thousands of genes
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics ...

Circular RNAs more common than previously thought
In the classical model of gene expression, the genetic script encoded in our genomes is expressed in each cell in the form of RNA molecules, each consisting of a linear string of chemical "bases". It may be time to revise ...

Study uncovers how DNA unfolds for transcription
(PhysOrg.com) -- The human genome contains some 3 billion base pairs that are tightly compacted into the nucleus of each cell. If a DNA strand were the thickness of a human hair, the entire human genome would ...

New research illustrates how genome adapts to transposon invasion
Small, mobile sequences of DNA left over from viruses, called transposons or "jumping genes" because of their ability to move around the genome, pose a significant threat to the genetic integrity and stability of an organism. ...

Researchers solve a protein complex's molecular structure to explain its role in gene silencing
A cell's genome maintains its integrity by organizing some of its regions into a super-compressed form of DNA called heterochromatin. In the comparatively simple organism fission yeast, a cellular phenomenon known as RNA ...

Waking up is hard to do: Scientists identify a gene important for the daily rhythms of the sleep-wake cycle
Northwestern University scientists have discovered a new mechanism in the core gears of the circadian clock. They found the loss of a certain gene, dubbed "twenty-four," messes up the rhythm of the common fruit fly's sleep-wake ...
