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 ...

Giorgia Guglielmi is a science journalist in Basel, Switzerland. The team also revealed the spatial organization of the mammoth’s DNA molecules and the active genes in its skin, including one ...

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 ...

“We’ve known that tiny fragments of ancient DNA can survive for long periods of time,” said Dr. Marcela Sandoval-Velasco of the Center for Evolutionary Hologenomics at the University of Copenhagen and ...

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 ...

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 ...

The field of genetics has evolved rapidly in recent years, however early understanding of inheritance patterns began much ...

Standard laboratory tests can fail to detect many disease-causing DNA changes. Now, a novel 3D chromosome mapping method can ...

Researchers identify a novel centromere-specific histone H3 variant called the “CENP-A”, which reconstituted with H4 forms “CENP-A–H4” octasome and explore its role in mitosis. Centromeres, ...

Neil Hunter, a professor in the Department of Microbiology and Molecular Genetics, has discovered a crucial step in how chromosomes stay connected during the development for egg cells and sperm, ...

"Our work is the first to directly test how chromosome structure affects bacterial growth, survival, and ability to cause disease, and it opens the door for similar studies in many other microbes," ...
