Researchers have found striking parallels between how archaeal cells and more complex cells, including humans' and animals', package and store their genetic material. The breakthrough study provided ...

Tokyo, Japan - Researchers from Tokyo Metropolitan University have successfully determined the high-resolution three-dimensional structure of proteins inside living eukaryotic cells. They combined "in ...

Our single-celled ancestor lived in a world without plants, animals or oxygen-rich oceans. Yet, this seemingly simple ...

A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). A typical ...

Researchers would like to better understand four-stranded RNA structures called RNA G-quadruplexes (RG4s), which are reported to play key roles in neurodegenerative diseases and cancer. Certain RNA ...

UT Southwestern and University of Washington researchers led an international team that used artificial intelligence (AI) and evolutionary analysis to produce 3D models of eukaryotic protein ...

Eukaryotes—the building blocks of complex life—appeared on Earth 1.7 billion years ago, and now scientists have solved a ...

Across all species, directed movement is essential for nutrient acquisition, energy harvesting, and the avoidance of danger or sources of stress. Organisms have evolved specific means of locomotion ...

Scientists are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors ...

The origin of eukaryotes is considered one of the greatest enigmas in biology: according to current doctrine, two prokaryotes, a so-called Asgard archaeon and a bacterium, are believed to have merged.

Nuclear magnetic resonance measurement and state-of-the-art computational science reveal protein structures in higher eukaryotic cells. Researchers from Tokyo Metropolitan University have successfully ...
