When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...
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 ...
On 22 May 2019, scientists from Queen's University boarded a modified Falcon 20 aircraft at Ottawa airport. Scheduled was a ‘vomit comet’ flight, where the plane repeatedly climbs to 8km in a steep ...
The first step in DNA replication requires the assembly of a group of proteins called the Origin Recognition Complex (ORC). Researchers have determined how the ORC assembles during the cell division ...
The universal features that define genomic regions acting as replication origins remain unclear. In this study, we mapped a set of origins in Trypanosoma brucei using stranded short nascent strand ...
Molecular combing provides unbiased quantification and characterization of DNA structure and dynamics by imaging single DNA molecules from cells, blood, and tissue samples. In this introductory ...
CHICAGO (July 25, 2008) – New research published in the July issue of the Journal of the American College of Surgeons shows elevated plasma DNA is a reliable marker of recurrent esophageal cancer. The ...
Inaccuracy of DNA replication poses novel health risk The researchers conclude that – combined with the greater radition risk in space – the inaccuracy of DNA replication under microgravity could pose ...
