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 ...

Extra chromosomes, found in some fish, contain copied genes that don’t work but can still impact the organism. Research shows ...

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 ...

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

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 ...

In about one out of every 800 people, two chromosomes fuse together to form an unusual bond. These are known as Robertsonian chromosomes. It's a mystery that has long stumped scientists. Now, ...

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 ...

Deep in coastal mangroves and even inside our own mouths, biologists are finding that DNA does not always sit in a simple loop at the cell’s center. A giant microbe called Thiovulum imperiosus has now ...

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 ...

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 ...
