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 ...

Researchers have found striking parallels between how archaeal cells and more complex cells, including humans' and animals', package and store their genetic material. The breakthrough study provided ...

Janelia researchers have uncovered a novel way that two of the structures inside cells-the endoplasmic reticulum (ER) and lysosomes-coordinate the production of proteins, highlighting how interactions ...

A ribosome is a complex macromolecular structure in the cell which is involved in the process of translation. This is an essential function of all living cells, allowing for the production of proteins ...

The chemical reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...
