Scientists unwind mystery behind DNA replication
The molecules of life are twisted. But how those familiar strands in DNA's double helix manage to replicate without being tangled up has been hard to decipher. A new perspective from Cornell physicists is helping unravel ...

'Proofreading' proteins stop and reel in DNA to correct replication errors
On the DNA assembly line, two proofreading proteins work together as an emergency stop button to prevent replication errors. New research from North Carolina State University and the University of North Carolina at Chapel ...

Genetic switch regulates transcription and replication in human mitochondria
(Phys.org)—The majority of the human genome is located within the nucleus. However, there is a small but important portion of DNA located within the mitochondria. This mitochondrial DNA (mtDNA) has received much attention ...
Researchers capture high contrast image of band of DNA fiber
(Phys.org)—A research team in Italy has succeeded in capturing a high contrast image of a band of DNA fiber – the closest anyone has ever come to taking a photograph of a single strand of DNA. The team has outlined the ...
How DNA 'proofreader' proteins pick and edit their reading material
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have discovered how two important proofreader proteins know where to look for errors during DNA replication and how they ...

Breaking up is hard to do (especially for sex chromosomes)
As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub. Its main purpose is to provide the instructions for initiating ...

'Unheard of in structural biology': New enzyme models reveal disease insights
When nucleic acids like DNA or RNA build up in a cell's cytoplasm, it sets off an alarm call for the immune system. Enzymes usually clear these nucleic acids before they cause an issue, but when these enzymes don't work and ...
