Standard cytogenetic techniques enable all human chromosomes to be stained and identified individually by their unique banding patterns. Routine cytogenetic analysis has a 400–500 band resolution and ...

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 ...

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 ...

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 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 ...

Michelle Starr is CNET's science editor, and she hopes to get you as enthralled with the wonders of the universe as she is. When she's not daydreaming about flying through space, she's daydreaming ...

Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks ...

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 ...

Agrobacterium tumefaciens magnified 15,000 times in an image captured earlier this year with a scanning electron microscope at Iowa State University's Roy J. Carver High Resolution Microscopy Facility ...

Sex chromosomes are chromosomes, or packages of DNA, that are found inside the nucleus of all of your cells. There are two different kinds: X and Y, which determine whether you’re biologically male ...

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.
