A team has unearthed new findings about what happens during the minutes and hours after a cell divides, expanding our understanding of human biology -- and potentially leading to better medicines.

Semiconservative replication was not the only model of DNA replication proposed during the mid-1950s, however. In fact, two other prominent hypotheses were put also forth: conservative replication ...

DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...

DNA replication is happening continuously throughout the body, as many as trillions of times per day. Whenever a cell ...

This experiment revealed a pattern that supports the semiconservative model of DNA replication. FURTHER RESEARCH: If you continued this experiment for two more generations (as Meselson and Stahl ...

Researchers at the University of Toronto have invented a new method that uses DNA sequencing to measure metabolites. This ...

suggesting that DNA replication problems are critical drivers of genomic instability that promotes aging and tumorigenesis. The Noguchi Lab works with mammalian cells and fission yeast ...

The team initially set out to study another replication machinery protein ... “This experiment is really the nail in the coffin of this model where everything is sitting stably on the DNA,” van Oijen ...

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...

The prevailing model suggests that BKPyV expresses a ... undetectable TAg expression before the first round of cellular DNA replication. Instead, there was a 100-fold increase in TAg levels ...

The study explores DNA damage and repair in neurons, which lack replication checkpoints due to their non-dividing nature. It reveals that DNA damage itself acts as a checkpoint, limiting genomic ...

The alternative model favors hydrothermal vents on the ... gas and water flow can trigger salt fluctuations which support DNA ...
