DNA replication is a fundamental process for a cell to ensure that an accurate copy of its genetic material is transmitted to daughter cells at each cell division. Challenges to 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 ...

Researchers have found that the “mother” of all stem cells, known as totipotent stem cells, have a much slower rate of DNA replication, which helps improve their efficiency at differentiating into ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Pictures of DNA often look very tidy—the strands of the double helix neatly wind around each other, making it seem like studying genetics should be relatively straightforward. In truth, these strands ...
