How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of 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 ...

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 ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still ...

A new study claims to have identified the first speakers of Indo-European language, which gave rise to English, Sanskrit and ...

Could a novel approach to genetic studies give us a clearer picture of how evolutionary adaptations occur? That's what the ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

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 ...
