The system involves two key components. CRISPR RNA is a molecule that guides the system to the specific DNA sequence that ...

Genetic changes can signal evidence of disease, but pinpointing which genes and what's changed can be difficult.

The discovery of four different subtypes of autism is a major step toward understanding the condition’s genetic underpinnings ...

It's known that female guppies prefer orange, and unusual, patterns in their male partners, but the team found that the color ...

I’ve lived like a lark for years — but my genes say I’m a night owl. Could changing my routine really change my life?

From schools of fish darting away from sharks to flocks of starlings swirling through the sky, the animal kingdom is full of ...

In Colombia’s Middle Magdalena region, a patchwork of forest corridors is linking up isolated populations of the critically endangered brown spider monkey (Ateles hybridus). Composed of native and ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Binary polymorphisms associated with the non-recombining region of the human Y chromosome (NRY) preserve the paternal genetic legacy of our species that has persisted to the present, permitting ...

Genetic variation as an adjustment to environmental changes. Genetic variation allows Chlamydia trachomatis to exploit diverse niches within a host (tissue tropism) and to avoid, escape or resist ...

Researchers have demonstrated a specific type of genetic variation in obsessive-compulsive disorder (OCD) for the first time using advanced DNA sequencing technology. The findings support previous ...
