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 ...

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

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 ...

Holocentric chromosomes have evolved independently from X-shaped monocentric chromosomes multiple times in both animals and plants, but the mechanism behind the centromere-type transition is unknown.

The iconic X-shaped organization of metaphase chromosomes is frequently presented in textbooks and other media. The drawings explain in captivating manner that the majority of genetic information is ...

For many years, scientists have delved into human chromosomes and the DNA they carry, studying the genetic code in each cell ...

The centromere is necessary for the transport of chromosomes during cell division and, therefore, for the correct transmission of genetic information. Most plants and animals have chromosomes with a ...
