Genome integrity in eukaryotic cells depends on the timely detection and faithful repair of DNA double-strand breaks (DSBs), which arise from exogenous insults, replication stress and programmed ...

How and when did cells gain the ability to crawl? Live imaging of cells from close relatives of early eukaryotes fills in a ...

An animal chromatin-diminution review examines measured genome and nuclear changes in copepods while treating the functions ...

In biology you must have come across the two types of cells, the prokaryotic and eukaryotic cells. These two are the most fundamental forms of life on earth. Everything living from the bacteria on ...

An investigation into cellular components in bacteria has unexpectedly uncovered a feature with relevance across many life forms, paving the way for diverse research, biotechnical and medical ...

Where did it start? How did it grow complex? Why did it get big? Three moments in Earth’s early history when evolution ...

An international collaboration has published groundbreaking research, shedding light on the most significant increase in complexity in the history of life's evolution on Earth: the origin of the ...

Back 2.8 billion years ago, while Earth shifted its plates to make new continents and violent volcanoes produced new crust, life crafted a novel invention of its own. 1,2 At first, the nucleus was ...

All cells in animals, plants, fungi, and protists share a fundamental characteristic: they are eukaryotic cells—complex cells with specialized internal compartments. The cells that make up our bodies ...

Prokaryotes are ancient, simple forms of life that include bacteria and archaea. These cellular life forms lack membrane-bound organelles. Those organelles, which include the nucleus and the ...

Current hypotheses suggest that all life on Earth evolved from a common ancestor that diversified into the variety of organisms seen today. Scientists propose that the eukaryotic branch of this family ...
