The structure of how DNA is stored in archaea makes a significant difference to how quickly it evolves, according to a new study by Indiana University researchers. The study, led by molecular ...

A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we've worked ...

Non-coding DNA is essential for both humans and trypanosomes, despite the large evolutionary divergence between these two species.

In 1963, Popular Science reported on the Nobel Prize-winning discovery, and the woman who was left out of the accolades. By Bill Gourgey Published May 31, 2022 7:00 AM EDT Get the Popular Science ...

Every new life begins after a genetic shuffle. When organisms make eggs or sperm, maternal and paternal chromosomes pair up and swap pieces of DNA in a process called crossing over. This exchange is ...
