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 ...
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 have made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in ...
As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...
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, ...
For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...
In a major leap forward for genetic and biomedical research, two scientists at the University of Missouri have developed a powerful new artificial intelligence tool that can predict the 3D shape of ...
One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we've worked ...
