In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes ...
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 ...
Cells are tremendously variable in their shapes and sizes, yet all cells share common properties. They all face the challenge of generating energy from food molecules that they will use to move, grow, ...
The origin of the nucleus remains hotly debated among scientists, but new imaging and genomic data are shedding light on this billion-year-old mystery.
All modern multicellular life — all life that any of us regularly see — is made of cells with a knack for compartmentalization. Recent discoveries are revealing how the first eukaryote got its start.

Ancient Microbes Fused Into Earth’s First Complex Cells. Scientists Learned What Made It Possible.
Around 1.7 billion years ago, eukaryotes—the building blocks of complex life—first appeared on Earth, and now scientists have ...
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, ...
The Cell World app is a nice educational app that is comprised of an interactive animation of the inside of a eukaryotic cell (as well as some rather hypnotic music). As users navigate around the cell ...
New studies revise ideas about the symbiosis that gave mitochondria to cells and about whether the last common ancestor of all eukaryotes was one cell or many. Our planet formed a little over 4.5 ...
A research team from the Faculty of Science, Charles University in Prague has discovered Solarion arienae, an extremely rare and morphologically unique unicellular eukaryote that sheds new light on ...
Perhaps as far back as the history of research and philosophy goes, people have attempted to unearth how life on earth came to be. In the recent decades, with exponential advancement in the fields of ...
