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 ...

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 ...

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 ...

An international research team has generated the first truly complete sequence of a human Y chromosome, the final human chromosome to be fully sequenced. The new sequence, which fills in gaps across ...

Centromeres act as the control centers of chromosomes, ensuring accurate genetic inheritance during cell division, yet they ...

Beef jerky and some woolly mammoths have at least one thing in common: Drying turns their DNA into super-tough glass. This glassy DNA is so stable that it preserved the three-dimensional structure of ...
