Ultra-deep long-read sequencing has delivered the first telomere-to-telomere sequence of the non-Mendelian ribosomal DNA ...
The ATR–ATRIP kinase complex safeguards genome integrity by coordinating cellular responses to DNA damage and replication stress. Two recent cryo-EM studies resolve the structural basis of ATR–ATRIP ...
Almost every cell in our body contains around two meters (6.6 feet) of DNA, packed into a tiny nucleus. Yet for the cell to ...
A cytogenetic study of 30 Quasipaa spinosa frogs from one Hunan farm found 26 chromosomes in both sexes, with nine ...
A team of researchers has uncovered a previously unknown mechanism that can disrupt DNA replication at the ends of chromosomes, shedding new light on one of the most fundamental challenges faced by ...
CD BioSciences, a service provider supporting biological aging research, recently announced its telomere length analy ...
"I've memorized 'meiosis.' But when asked about the number of chromosomes, I get it wrong."Have you ever felt that way when looking at your child's test answers?They know it "becomes half." But they ...
In cell division, one cell becomes two.”Your child might be able to answer up to this point.However, when it comes to questions about arranging diagrams of the division process in order or answering ...
DNA can be more than just a double helix. When four strands are folded into a compact bundle, they form a G-quadruplex (G4). These bundles form in guanine-rich regions across the genome, including ...
Faithful DNA replication requires not only copying genetic information but also restoring the packaging and organization of DNA, particularly within highly compact heterochromatin regions. We show ...
Add Yahoo as a preferred source to see more of our stories on Google. A Japanese research team has demonstrated that CRISPR-Cas9 can selectively remove the extra copy of chromosome 21 from cells ...
