Termination of DNA replication occurs when two replication forks meet on the same stretch of DNA, during which the following events occur, although not necessarily in this order: forks converge ...

Scientists see the first steps of DNA unwinding Scientists report the most detailed account yet of the very first steps in DNA replication, an event that all life uses to grow and reproduce Peer ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

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

Today, researchers are making steps toward a full understanding of the molecular checks and balances that have evolved in order to ensure that each origin initiates DNA copying once and only once ...

Almost all life on earth is based on DNA being copied, or replicated, and understanding how this process works could lead to a wide range of discoveries in biology and medicine. Now for the first time ...

How does the DNA replication process start? Scientists provide the first snapshot of how double-helix DNA begins to unwind and replicate.

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it?

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

DNA replication and repair are critical processes that ensure the correct genetic material of a biological system is carried on. DNA continually undergoes a process of replication and division and ...

DNA repair and replication pathways converge on a common final step in which the continuity of the repaired DNA strand is restored by DNA ligase, an enzyme that converts nicks into phosphodiester ...
