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 ...

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 ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the ...

“Genìa Da Vinci,” by Alessandro Vezzosi and Agnese Sabato, is published by Angelo Pontecorboli Editors with the support of the Richard Lounsbery Foundation and under the patronage of the Municipality ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

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 ...

“This is the first detailed study of how and where ORC regulates epigenetics and gene expression in human cells,” said Anindya Dutta, Ph.D., leader of the study and chair of the University of Alabama ...

For more than five centuries, Leonardo Da Vinci has been celebrated as a visionary artist, scientist, and inventor, known for his extraordinary talent and groundbreaking experiments. Today, an ...
