In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.

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 ...

The discovery of giant viruses has changed what we thought we knew about microbes. Researchers have now learned more about giant viruses that can infect bacterial cells, so-called jumbo phages.

This article was originally featured on Knowable Magazine. More than 1.5 billion years ago, a momentous thing happened: Two small, primitive cells became one. Perhaps more than any event—barring the ...

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, ...

For foreign DNA to make it into a eukaryotic cell’s genome, DNA must first enter the cell, then cross the nuclear envelope, and finally insert itself into the genome. Below are a number of proposed ...

In mammalian cells, besides nuclei, mitochondria are the only semi-autonomous organelles possessing own DNA organized in the form of nucleoids. While eukaryotic nuclear DNA compaction, chromatin ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

Genomes contain the complete library of information required to build and maintain a living organism—the figurative blueprints of life. In eukaryotes, genomes are stored in the nuclei, where they are ...

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 ...
