Focusing on the schematic illustration in a, two DNA polymerase molecules are active at the fork at any one time. One moves continuously to produce the new daughter DNA molecule on the leading strand, ...
Two sibling DNA polymerases synthesize most of the eukaryotic nuclear genome. A new study provides insights into the distinct protein interactions that deliver these replicases for asymmetric leading- ...
DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...
On their own, however, polymerases aren't good at staying on the DNA strand. They require CTF18-RFC in humans and Ctf18-RFC in yeast to thread a ring-shaped clamp onto the DNA leading strand, and ...
During replication, DNA polymerases are positioned on each strand of DNA . Using a microscope slide as an anchor, we tethered DNA to a bead and stretched it with a flow of solution. We tracked how the ...
If the engines of DNA replication stay in high gear all the time, they eventually stall or even break down. Fortunately, these engines, which consist of protein complexes, have what could be called ...
Balancing act of a leading strand DNA polymerase-specific domain and its exonuclease domain promotes genome-wide sister replication fork symmetry. Meng X, Claussin C, Regan-Mochrie G, Whitehouse I, ...
Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres ...
A new study published in Nature Structural & Molecular Biology reveals how the fundamental enzyme called DNA polymerase delta operates during DNA replication, making a copy of the genetic code that ...
