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 ...

THE structure of DNA is now known and the external form of mitotic chromosomes of higher organisms is fairly well characterized in the light microscope. However, the way in which chromosomes are ...

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 ...

A team of scientists studying cell division developed a special light microscopy system and used it to analyze the molecular density of cellular environments. Their results provide a novel insight ...

Many animals use a special pair of chromosomes to determine their sex during development, but how did this system evolve? Where did these chromosomes come from and how do they change over time?

The M25 multi-focus microscope uses separate cameras to capture images from 25 focal planes at different depths in a sample. (Photo by Eduardo Hirata) The aberration-corrected multi-focus microscopy ...

WASHINGTON — Some cancers are addicted to having extra chromosomes, a study in mice suggests. Cells usually have just two copies of each chromosome — one inherited from mom and one from dad. But about ...

In Denmark, more and more people are experiencing problems with fertility. In more than half of the miscarriages that occur during the first 12 weeks, it is because the fetus has a chromosome defect.

The soil roundworm Caenorhabditis elegans has just 959 cells and a body that is mostly gut and reproductive organs. Yet its reproduction is similar enough to ours that scientists like Francis McNally ...
