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 ...

American Journal of Botany, Vol. 27, No. 8 (Oct., 1940), pp. 683-686 (4 pages) Metaphase and anaphase chromosomes of the second reduction division of Gasteria spp. hitherto considered as displaying an ...

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.

Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the ...

Scientists have mapped out the molecular structure of a key part of our chromosomes called telomeres, which play a pivotal part in aging and cancer. Scientists from Nanyang Technological University, ...

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 ...

Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) have identified key changes to both chromosome structure and gene expression that affect stem cell function during aging. Using ...
