A new article analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study demonstrates that the multilaminar ...

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 ...

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

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 ...

Previously, researchers from Tianjin University designed and created a 254 kb digital data carrying artificial chromosome in yeast. This work “is a key proof-of-concept that demonstrated how ...

Mitotic chromosomes are pivotal for the inheritance of genetic material. Now, it is already known that chromosomes vary in dimensions among organisms. But what governs mitotic chromosomal size and ...

In response to DNA damage, chromatin undergoes a global decondensation process that has been proposed to facilitate genome surveillance. However, the impact that chromatin compaction has on the DNA ...

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 ...

New study shows that chromosomes of carnivores (cats, dogs and bears) show similar 3-D structures despite being separated by over 50 million years of evolution. Photo credits: Clouded leopard, ...
