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 ...

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 ...

An unassuming butterfly called the Atlas blue has been confirmed to have the greatest known number of chromosome pairs of any ...

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 ...

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 ...

Researchers are making strides in understanding how chromosome structures change throughout the cell's life cycle. Researchers at Rice University are making strides in understanding how chromosome ...

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 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, ...

During sexual reproduction, haploid gametes (i.e. eggs and sperm) are generated from diploid precursors through the specialized cell division of meiosis. Meiosis reduces ploidy by following one round ...
