Jenny Graves receives funding from the Australian Research Council. If you look at cells from a human or other mammal under a microscope, you’ll see big fat molecular complexes called chromosomes that ...

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 ...

Researchers from Tokyo Metropolitan University have developed a suite of algorithms to automate the counting of sister chromatid exchanges (SCE) in chromosomes under the microscope. Conventional ...

Scientists have taken a detailed look inside the small, densely packed structure of the inactive X chromosome found in female mammals called the Barr body. Scientists at UMass Medical School, the ...

Information on the sex chromosome content of sperm has been obtained from studies using differential staining methods, sperm karyotyping, and in situ hybridisation. So far each of these techniques has ...

For the first time, researchers see how proteins grab loops of DNA and bundle them for cell division. The discovery also hints at how the genome folds to regulate gene expression. A human cell carries ...
