Vibrio cholerae presents a unique model of bacterial genome organisation through its bipartite genome, comprising two distinct chromosomes that replicate in a carefully orchestrated manner. The ...

The initiation of chromosome replication is exquisitely regulated in both time and location. It has been estimated that there are 200-400 autosomal replication sequence elements (ARSs) in the yeast ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

During the replication of the bacterial chromosome, genes close to the replication start point (red) exist in multiple copies, while genes close to the endpoint do not (blue). At faster growth, this ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA – its genome – and segregate it equally ...

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...
