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 ...

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 ...

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 ...

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 ...
