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 ...

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 decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

Giorgia Guglielmi is a science journalist in Basel, Switzerland. The team also revealed the spatial organization of the mammoth’s DNA molecules and the active genes in its skin, including one ...

In a major leap forward for genetic and biomedical research, two scientists at the University of Missouri have developed a powerful new artificial intelligence tool that can predict the 3D shape of ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

Researchers are making strides in understanding how chromosome structures change throughout the cell's life cycle. Researchers at Rice University are making strides in understanding how chromosome ...
