In all living organisms, DNA replication is essential to ensure the genetic fidelity of the next generation. However, bacteria can also transfer genetic information horizontally to other bacteria.

This story is part of our series on viroids and virusoids, small infectious RNAs. The story is also the second installment in a series on hepatitis D virus, a virusoid-like pathogen that causes ...

Bacteriophages deploy streamlined yet robust strategies to replicate their DNA within host cells. Replication typically initiates at defined viral origins recognised by phage-encoded initiator ...
