New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

Deoxyribonucleic acid (DNA) replication is fundamental to life, yet the precise mechanics of how helicases unwind the genome for replication remain unclear. A recent study published in Nature used ...

When not undergoing replication, DNA molecules float freely within the cytoplasm of a cell. This makes them available to the ...

For the first time, scientists have sequenced the oldest and complete DNA set of an ancient Egyptian man, dating to when the ...

Their findings, which were published March 7 in Science, one of world’s leading scientific journals, not only reveal new details about how secondary DNA structures like G4s can impede DNA replication, ...

Without enough materials, you can't replicate DNA at the same speed, which also slows down the replication process. So, there are a lot of different causes. I've touched on two major ones.
