A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

A research team from the Faculty of Science, Charles University in Prague has discovered Solarion arienae, an extremely rare ...

Figure 1: Structure and enzymatic synthesis of the m 7 G cap of eukaryotic mRNA. The universal phylogenetic tree that was proposed by Carl Woese and colleagues 2 comprises three evolutionary domains — ...

A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...

As a fundamental unit of life, the cell is central to all of biology. Better understanding how complex cells evolved and work promises new revelations in areas as diverse as cancer research and ...

An exchange of genetic material that occurred when ancient giant viruses infected ancient eukaryotic cells could have caused the nucleus of the eukaryotic cell -- its defining feature -- to form. A ...

In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the ...

Previously, chemists have managed to create artificial cell walls and developed synthetic DNA to produce self-replicating, synthetic bacterial cells. Now, for the first time, researchers have used ...

At each cell division in humans, DNA replication starts from 50,000 DNA replication origins, which are at specific locations along the chromosomes and from which DNA synthesis proceeds bidirectionally ...

The cell is the structural and functional unit of living organisms. It was discovered by Robert Hooke in 1665. Cell in Latin means “little room”. Many organisms, such as bacteria, protozoa and yeasts ...
