Beneath the surface of present-day western Honduras lie the ruins of Copán—an archaeological site that once stood as a vital ...

At some point, RNA must have replicated itself before the evolutionary arrival of DNA and proteins, and now we might know how ...

Additionally, the scientists unexpectedly captured for the first time a detailed picture of how the "engine" driving the cellular replication machinery moves along DNA in human cells. Their ...

By knocking out TEFM, they observed a notable reduction in mtDNA copy number, alongside a decrease in 7S DNA levels and strand-asynchronous replication intermediates. These findings suggest that TEFM ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues ...

If parent cells and their daughter cells are to share a stable identity, parent cells must divide—and replicate their DNA—while ensuring that their histones are distributed properly to their ...

The findings visualize for the first time a molecular complex -- called CTF18-RFC in humans and Ctf18-RFC in yeast -- that loads a 'clamp' onto DNA to keep parts of the replication machinery from ...

DNA Strand Mismatch Repair During the process of DNA replication, errors can sometimes occur. Nucleotide bases may be inserted, deleted, or mismatched into the DNA strand incorrectly. For this ...

But Surman points out that there are limitations to the self-replication; specific DNA chains are required as raw material for the process to work, as well as certain organic molecules ...

Researchers have gained a clearer insight into how common alterations to the structure of DNA affect the process of DNA replication. These structural changes can put a stop to replication, causing ...
