In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

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, ...

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

These sequences are extremely prone to mutations and rank among the most functionally important regions in the entire human ...

It's a common storytelling trope: the stubborn foe who is eventually revealed to be a much-needed friend. Biology has its own ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...
