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 ...

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 ...

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 ...

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 ...

Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks ...

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 ...

Chromosomal rearrangements, such as chromosome segment inversions, may affect the epigenetic landscape as well as gene expression. Different kinds of chromosome segment inversions have been found in ...
