A new method for visualising chromosomes is painting a truer picture of their shape, which is rarely like the X-shaped blob of DNA most of us are familiar with. Scientists at the BBSRC-funded Babraham ...

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 ...

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 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 improper segregation of chromosomes during cell division leads to abnormalities that disrupt the proper functioning of the cell. Cells with an abnormal number of chromosomes consequently activate ...

“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 2018, a 52,000-year-old woolly mammoth was found preserved, complete with skin and muscle, in the Siberian permafrost. Scientists used a new technique, called Hi-C, to analyse the 3D structures of ...

SEM images of male and female human aortic valve tissue samples from two healthy patients and two patients diagnosed with AVS. Scale bars, 5 micrometers. A study led by bioengineers at the University ...

Researchers have shed new light on how a type of heart valve disease -- aortic valve stenosis -- progresses differently in males and females. A study led by bioengineers at the University of ...
