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 ...

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 ...

Researchers used advanced technology to analyze DNA elements that control gene expression ... Enhancers, which boost gene transcription, were active regardless of their orientation and exhibited ...

You need a source (to play the music), an amplifier (to necessarily strengthen the audio signals) and a pair of speakers (to output it). But each job doesn't necessarily require a separate box; active ...

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.

A 2015 report published by a private genomics testing company found that 2% of 345 hot dogs tested contained traces of human DNA. However, it was unclear whether that report was a peer-reviewed ...

Dysregulation of synaptic plasticity gene expression affects memory during aging and neurodegenerative diseases. Covalent modifications such as methylation on DNA and acetylation on histones regulate ...

Epigenetic inheritance concerns the mechanisms that ensure transmission of epigenetic marks from mother to daughter cell. Chromatin modifications and nuclear organization are candidates for ...
