The origins of complex, nucleated cellular life – everything from amoebas to humans – may date back a lot further in Earth's ...

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning “true kernel”) have a cell nucleus that harbours most of the cell’s genetic information and ...

The Archaea was recognized as a third domain of life 40 years ago. Molecular evidence soon suggested that the Eukarya represented a sister group to the Archaea or that eukaryotes descended from ...

Complex life, eukaryotes, traces its origins to a shared ancestor among the Asgard archaea, reshaping our understanding of how life evolved.

As eukaryotic cells started to form, eukaryotic traits may have emerged in early cells about one billion years before the ...

For billions of years after the origin of life, the only living things on Earth were tiny, primitive cells resembling today’s bacteria. But then, more than 1.5 billion years ago, something remarkable ...

A lot happened in the hundreds of millions years separating the first and last eukaryotic common ancestors, but when and how most features arose remains a mystery. Eukaryogenesis is broadly defined as ...

All complex life forms on Earth, including plants and animals, are made up of eukaryotic cells; they are more sophisticated than bacterial or archaeal cells, which are prokaryotic. Eukaryotes have ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 105, No. 41 (Oct. 14, 2008), pp. 15950-15955 (6 pages) Ser/Thr/Tyr kinases, which together comprise a major class ...

The Argonaute (Ago) enzyme complex plays a critical role in DNA and RNA target cleavage for a process known as RNA silencing in prokaryotic and eukaryotic cells, making them a target for future ...
