Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important ...

In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called the nucleus. Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear ...

Fossil evidence of how the earliest life on Earth came to be is hard to come by. But scientists have come up with a few ...

On the other side there are the huge and unwieldy eukaryotes, the third great domain of life. A typical single-celled eukaryote, such as an amoeba, is about 15,000 times larger than a bacterium ...

Bacteria are amongst the simplest of organisms – they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi.

Scientists knew from previous studies that eukaryotes had evolved by this time, but their diversity in this era was poorly ...

This study is published in Current Biology. Eukaryotic cells rely on dynamic shape changes to fulfill various cellular functions, sustain vital biological processes, and regulate cellular behavior.

What is Bioinformatics? The definition of bioinformatics is currently controversial, but bioinformatics can be loosely defined as the use of computers and computer science to study biological ...

At this time, biological diversity increases greatly, with algae, fungi, animals, and plants diverging from their common eukaryote ancestors. The oldest fossil evidence of multicellular animals ...

Our goal is to define the cell cycle program of chromosome movement in E. coli using a cell cycle synchronization apparatus we designed called the “baby cell machine." Chromosome Cohesion: In ...
