Endosomal recycling is a branch of intracellular membrane trafficking that retrieves endocytosed cargo proteins from early and late endosomes to prevent their degradatio ...

CRISPR/Cas9 works using a Cas9 enzyme and a guide RNA. Lau compared the guide RNA to a global positioning system (GPS) that scans the genome and leads the Cas9 to cut DNA at a specific sequence ...

A new study in the journal Nature throws a new theory into the fray. Analyzing a wealth of DNA collected from fossilized human bones, the researchers found that the first Indo-European speakers ...

Ancient DNA locates the geographic origin of Proto-Indo-Europeans and Proto-Anatolians and describes their early migrations out of the Caucasus Lower Volga and North Pontic regions of present-day ...

Kids rushed home to watch classic cartoons like Popeye, The Powerpuff Girls, and Pokémon, while playing with Tamagotchis and collecting Pokémon cards. The era also brought influential music ...

1 CRISPR-Cas systems utilize RNA guides to direct Cas proteins to specific DNA sequences, where the Cas protein cleaves the DNA. This ability to precisely target and cut DNA is the foundation for ...

To start, the team cultured cells with sperm DNA to collect stem cells in the lab. Then they used CRISPR to disrupt the 20 imprinted genes they were targeting. These gene-edited cells were then ...
