AMES, Iowa – A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, ...

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 ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene ...

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive structural supports. But a new study reveals they play a far more active signaling ...

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 ...

The complete assembly of each human chromosome is essential for understanding human biology and evolution. Using complementary long-read sequencing technologies, we complete the first linear assembly ...

Scientists at the Stowers Institute for Medical Research have, for the first time, identified the exact location where human chromosomes break and fuse to form Robertsonian chromosomes. The discovery ...

Scientists from the Kavli Institute of Delft University of Technology and the IMP Vienna Biocenter discovered a new property of the molecular motors that shape our chromosomes. While six years ago ...
