Chromosome segregation and site-specific recombination are central processes in bacterial cell division and genome maintenance. The orchestration of these events ensures that circular chromosomes are ...

Bacterial chromosome dynamics and gene regulation are intimately linked through a finely orchestrated interplay between the physical organization of the chromosome and the molecular processes that ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

A system once tied to DNA organization in cyanobacteria has evolved into a structure that shapes the cell itself. This shift ...

There are photosynthetic bacteria known as cyanobacteria, and these microbes helped generate the oxygen that paved the way ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

For a living cell to divide successfully, each daughter cell must inherit the correct genetic material. In eukaryotes, segregation of duplicated chromosomes is performed by the mitotic spindle, a ...

A subtle failure during cell division can set off dramatically different outcomes, according to new research exploring whole genome duplication. A new study finds that the way a cell fails to divide ...

Photosynthetic bacteria helped shape planet Earth. Among them are cyanobacteria that produced the oxygen in the atmosphere and made complex life possible, captivating scientists for decades. Now, ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...
