One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

Among scientists, it is widely accepted that the structure of genomes largely controls their transcriptional activity within the cell. Structural features known as chromatin are responsible for this ...

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 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 ...

A new study challenges prevalent models of chromosome formation during mitotic cell division. The study compared the dimensions of chromosomes in yeasts and humans and found that not only is the width ...
