UCLA researchers determined sperm carrying a Y chromosome swim differently than sperm carrying an X chromosome. In a study published October, Aydogan Ozcan, professor of electrical and computer ...

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 ...

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 ...

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 ...

Modern genetics reveals that over 50 genes across many chromosomes—not just X and Y—govern sex development. The term “sex ...

Scientists at Fred Hutchinson Cancer Research Center have worked out the molecular underpinnings of how chromosomes make the right number of crossovers — important links that make it possible for ...

She had to fight for recognition after a male colleague took credit for her work in identifying an extra chromosome as the cause of that genetic condition.

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 ...

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 ...

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.

Abnormalities in the structure of chromosomes within someone’s genetic makeup are called structural chromosomal abnormalities. Robertsonian translocations are very rare structural chromosomal ...
