DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Hidden RNA Inside a Gene Solves Decades-Old Telomere Mystery in Roundworms

An international research team led by Hiroki Shibuya at RIKEN Center for Biosystems Dynamics Research (BDR) in Japan has solved a genetic mystery and revealed a previously unknown way that DNA can control what cells do.

New Retron-Based Gene Editing Method Corrects Multiple Disease-Causing Mutations

Some genetic disorders-such as cystic fibrosis, hemophilia and Tay Sachs disease-involve many mutations in a person's genome, often with enough variation that even two individuals who share the same disorder might have a different combination of mutations.

Breakthrough Cryo-EM Study Maps Herpes Replication Protein in New Detail

An international research team has successfully identified the initial high-resolution structures of the herpes simplex virus origin-binding protein (OBP), which is an essential element in viral DNA replication that has remained structurally uncharacterized for the past forty years.

Croatian Scientists Rewrite the Story of Cell Division

Scientists at the Ruđer Bošković Institute (RBI) in Zagreb, Croatia, have discovered that the protein CENP-E, long believed to act as a motor dragging chromosomes into place during cell division, in fact plays a completely different role in chromosome movement.

Disarming Cancer’s Droplet Hubs to Halt Tumor Growth

In a city, coworking hubs bring people and ideas together. Inside cancer cells, similar hubs form-but instead of fueling progress, they supercharge disease. That's what researchers at the Texas A&M University Health Science Center (Texas A&M Health) have discovered inside the cells of a rare and aggressive kidney cancer.

Cancer Reawakens Embryonic Gene Editors to Fuel Tumor Growth

Cancer cells are known to reawaken embryonic genes to grow. A new study reveals the disease also hijacks the proteins, or "editors", that control how those genes are read.
