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 ...
When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...
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 ...
A new computational tool infers changes occurring at the ends of the chromosomes housing our DNA. It does so by detecting structural alterations in cells and tissues captured in images taken of ...
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 ...
When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction ...
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 ...
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 ...
