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 ...

A research group led by Drs. Shusuke Tada and Takashi Tsuyama at the Department of Molecular Biology, Faculty of ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Small, cancer-associated DNA circles "hitchhike" on chromosomes during cell division to spread efficiently to daughter cells ...

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 ...

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 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 ...

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 ...
