The origins of life on Earth have long fascinated scientists, particularly the nature of the last universal common ancestor ...

An exciting new study reveals that life on Earth might have already flourished within a few hundred million years of the ...

Co-author Professor Davide Pisani said: “Our study showed that LUCA was a complex organism, not too different from modern prokaryotes, but what is really interesting is that it’s clear it ...

To date, NLS-motifs have been characterized in ten ribosomal proteins from several eukaryotic species. They compared all of the NLS-motifs found in eukaryotic ribosomal proteins (from 482 species ...

Catching genes from chlamydiae allowed complex life to live without oxygen Date: August 26, 2020 Source: Uppsala University Summary: Researchers has discovered a new group of Chlamydiae - named ...

Because all complex life today can be traced to a single eukaryotic branch of the evolutionary tree, it has been assumed that this chance endosymbiotic event, the acquisition of mitochondria ...

Modern nucleated (eukaryotic) cells use specialized protein scaffolds to ensure chromosomes segregate properly into daughter cells, with each daughter receiving one copy of each chromosome.

In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and ...

Norman Pace has a problem with prokaryotes. It’s not that Pace has anything against the organisms themselves. The microbiologist and RNA scientist from the University of Colorado at Boulder has ...

A newly discovered life form could help resolve one of the most contentious conundrums in modern biology. All organisms on Earth are classified as either prokaryotes, which have simple cells, or ...
