Scientists at UCL and the MRC Laboratory of Molecular Biology have recreated how RNA might have first replicated itself on ...
At some point, RNA must have replicated itself before the evolutionary arrival of DNA and proteins, and now we might know how ...
This landmark study describes the structure of the human RAD51 filament with a recombination intermediate called the displacement loop (D-loop). Using cryogenic structural, biochemical, and ...
Researchers unveil the fractal globule structure of DNA, providing new insights into genome organization and its implications ...
If DNA bridges persist between chromosomes during cell division, chromosomes are abnormally segregated, leading to genetic ...
When organisms encounter problems -- what scientists call "replication stress ... bases (represented by G in the DNA code) can fold into a DNA structure called a G-quadruplex, or G4 for ...
"The replication process is carried out ... G-quadruplex–stalled eukaryotic replisome structure reveals helical inchworm DNA translocation, Science (2025). DOI: 10.1126/science.adt1978 ...
Each time a part of a chromosome unwinds for replication, regions of DNA unzip, forming a structure that looks like a fork in the road. For replication to proceed, the fork must move down the ...
each of which varies depending on its specific structure. The most common is B-DNA, but some other types found in the genome include A-DNA, H-DNA, and Z-DNA. DNA replication is a process that ...
The diagram below illustrates the process nicely. As DNA replication begins running through each base pair on its recipe list, it stops when it hits a mutation or faulty base pair. Replication then ...
Researchers have demonstrated a programmable nano-scale robot, made from a few strands of DNA, that's capable of ... can "self-replicate its entire 3D structure and functions." ...
But that structure could also be designed to ... But Surman points out that there are limitations to the self-replication; specific DNA chains are required as raw material for the process to ...
