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 ...

Researchers have made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in ...

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 ...

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 ...

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 ...

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 ...

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 ...

Scientists have mapped out the molecular structure of a key part of our chromosomes called telomeres, which play a pivotal part in aging and cancer. Scientists from Nanyang Technological University, ...

The field of genetics has evolved rapidly in recent years, however early understanding of inheritance patterns began much ...

“Our work is the first to directly test how chromosome structure affects bacterial growth, survival, and ability to cause ...
