Eukaryotes are organisms whose cells possess a nucleus enclosed within a cell membrane, making up one of the three domains of life, Eukaryota. They include multicellular organisms such as plants, ...

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 ...

Enzymes have clearly defined active sites to allow the substrate molecule to fit intricately. This is often coupled with an enzymatic conformational change prior to the occurrence of the catalysis ...

Maybe the first life on Earth was part of an 'RNA world.' Artur Plawgo/Science Photo Library via Getty Images How life on Earth started has puzzled scientists for a long time. And it still does.

Eukaryotes—fungi, plants, us—are complex. Our large cells are characterized by their different compartments, many of which are neatly enclosed within a boundary of membrane. These compartments contain ...

You wake up one morning achy, with fever, chills, a stuffy nose and a cough. A virus has performed a hostile takeover of your cellular machinery to manufacture its own proteins and replicate itself.

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 ...

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 ...
