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 ...

Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

A new study has found that the photosynthetic bacterium Synechococcus elongatus uses a circadian clock to precisely time DNA replication, and that interrupting this circadian rhythm prevents ...

A team of researchers has generated one of the most detailed 3D maps of human chromosomes, cataloging over 140,000 DNA looping interactions.

Small, cancer-associated DNA circles "hitchhike" on chromosomes during cell division to spread efficiently to daughter cells by co-opting a process used to maintain cellular identity through ...

Jenny Graves is a Friend of The Conversation. Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are ...

Spontaneous errors in the earliest phase of cell division may be the reason why so many human embryos fail to develop normally, according to new research. In humans, a fertilized egg is no guarantee ...

A study on Y chromosome loss titled "Hematopoietic loss of Y chromosome leads to cardiac fibrosis and heart failure mortality" has been published in the journal Science. Researchers from the Osaka ...
