Arthur Kornberg compared DNA to a tape recording of instructions that can be copied over and over. How do cells make these near-perfect copies, and does the process ever vary?

The whole process of DNA replication, in human cells, takes about eight hours. There is still plenty to be worked out. For one thing, the DNA that’s being copied is not a naked double helix.

Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

A scientific team says it have pinpointed the crucial steps in the beginning of the DNA replication process, including surprising structural details about the enzyme that unzips and splits the ...

To get there, many other steps of DNA replication still need to be understood, such as how the melted DNA origin is opened up even more fully to produce the Y-shaped DNA replication fork. “The DNA ...

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 ...

Nareg Djabrayan, an associate research scholar at the Lewis-Sigler Institute for Integrative Genomics and first author of the paper, likened the replication process to a machine. “When you provide ...
