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, ...

The main difference between prokaryotic and eukaryotic cells lies in their structure. Prokaryotic cells and eukaryotic cells are the two types of cells that exist on Earth. There are several ...

mRNA 5′ untranslated regions (UTRs), which serve as the entry point for the ribosome during translation, can adopt elaborate RNA secondary and tertiary structures that may regulate translation ...

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 ...
