How do bacteria, lacking a nucleus, organize and pack their genome into the cell? Supercoiling enables this but forces a different kind of transcription and translation in prokaryotes. Aa Aa Aa ...

In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell's DNA is housed and ...

The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus. The nucleus is ...

The International Committee on Systematics of Prokaryotes recently pulled the rank of phylum into its code of official nomenclature. Experts say the move will help standardize science in the long run ...
