Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren’t ...
The most accurate quantitative model yet for understanding the role of condensin during cell division is also visually stunning. A team of scientists from UT Austin have developed the most accurate ...
Researchers created artificial kinetochore structures that reduce chromosome separation errors during meiosis in aging egg cells. By lowering microtubule pulling force, the approach helped maintain ...
In early cytological studies chromatids of metaphase chromosomes were suggested to coil into a spiral called chromonema. This assumption was recently supported by chromosomce conformation capture ...
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...
A study by Zhiyu Cao, left, and Peter Wolynes, right, was recently published in PNAS. Researchers at Rice University are making strides in understanding how chromosome structures change throughout the ...
When a woman becomes pregnant, the outcome of that pregnancy depends on many things—including a crucial event that happened while she was still growing inside her own mother's womb. It depends on the ...
For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...
New research reveals that ancient interbreeding between humans and Neanderthals shaped our modern human DNA - especially on the X chromosome.
