Researchers have revealed new details about the CRISPR-Cas5-HNH/Cascade complex, a variant of the type I-E CRISPR-Cas system, ...

In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive organelles, such as micro-compartments found in some bacteria, help organize cellular processes by concentrating ...

Hydrogels are polymeric materials with three-dimensional network structures containing large amounts of water. They serve as sustained-release drug delivery systems as they can encapsulate various ...

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA clearance following damage, driven by the exonuclease activity of the mtDNA ...

The high accuracy or fidelity of semi-conservative DNA replication is the product of nucleotide template interaction, polymerase-enhanced base selectivity, exonuclease proofreading and the post ...

A new research paper was published in Aging (Aging-US) on January 3, 2025, in Volume 17, Issue 1, titled "Characterization of DNA methylation clock algorithms applied to diverse tissue types." ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

According to a statement released by the University of New Mexico, researchers led by Pere Gelabert and Victoria Oberreiter ...

For decades, the leading theory for the ubiquity of Indo–European languages was that early farmers, living in a region known ...

Ancient-DNA analyses identify a Caucasus Lower Volga people as the ancient originators of Proto-Indo-European, the precursor ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...
