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 ...

Changes in genes have been linked to the development of different diseases for a while. However, it's not exactly clear what ...

Non-coding DNA is essential for both humans and trypanosomes, despite the large evolutionary divergence between these two species.

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 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 ...

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 ...

Human fertility hinges on a delicate molecular ballet that begins even before birth. UC Davis researchers have uncovered how special protein networks safeguard chromosomes as eggs and sperm form, ...

Researchers at The Institute of Cancer Research, London identified the CIP2A–TOPBP1 complex as a master regulator of DNA repair during mitosis, coordinating backup pathways that protect chromosomes ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

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 ...
