In the late 1970’s, our understanding of the tree of life was fundamentally changed with the discovery and recognition of Archaea, a third domain of life along with Bacteria and Eukarya. While ...

The three domains of life — archaea, bacteria, and eukarya — may have more in common than previously thought. The three domains of life -- archaea, bacteria, and eukarya -- may have more in ...

Three domains of living things, archaea, bacteria, and eukarya, are organized by shared characteristics fundamental to life: cellular organization, biochemistry, and molecular biology. However, these ...

Life as we know it has been classified into three domains - Archaea, Bacteria, and Eukarya. The first two domains include single-celled organisms that do not have a nucleus, and there were thought to ...

Earth’s first life forms eventually took one of three different paths, forming the domains of Eukarya, Bacteria, and Archaea. These domains have been evolving separately for billions of years. Recent ...

The tree of life is broken up into three domains: Bacteria, Eukarya and Archaea. Bacteria are tiny, simple cells with no nucleus. Eukaryotes, by contrast, keep their DNA in a nucleus and have ...

Earth is home to an estimated 8.7 million species, only a fraction of which have been scientifically identified. However, despite this vast, disparate tree of life, every living thing falls into one ...

In the world of microbes, as in politics, some groups just can't seem to shake the label ''extremist.'' So it is with archaea (ar-KEY-uh), a collection of bacteria-like microorganisms whose unique ...

Methanosarcina acetivorans belongs to the Archaea which constitute the third domain of life, alongside Bacteria and Eukarya; the term Eukarya comprising all living organisms with a cell nucleus ...

His research is focussed on DNA replication, recombination, and repair. He has used microbial genetics to unravel the mechanisms that underpin genome stability in Bacteria, Eukarya, and Archaea.
