An elusive step in the process of human DNA replication has been observed, for the first time, by scientists. The step, which is crucial for DNA replication in humans and other forms of life, had ...

Part of the DNA replication process -- in humans and in other life forms -- involves loading of molecular structures called sliding clamps onto DNA. This crucial step in DNA replication had remained ...

This article describes the organization of mitochondrial DNA into nucleoids and the replication process, including initiation, elongation, termination and the involvement of polymerase enzymes.
