The improper segregation of chromosomes during cell division leads to abnormalities that disrupt the proper functioning of ...

This step decreases the possibility that the resulting daughter cells will have unbalanced numbers of chromosomes — a condition called aneuploidy. How Do Scientists Study the Cell Cycle?

"When a cell is aneuploid, it has an altered set of chromosomes," explains Storchová. A well-known example of aneuploidy is found in people with Down-Syndrome, who have an extra copy of ...

Aneuploidy occurs when there are either too many or too few chromosomes in cells. Down syndrome, for example, is caused by a trisomy—three copies instead of two—of chromosome 21. Amniocentesis and ...

“When a cell is aneuploid, it has an altered set of chromosomes,” explains Storchová. A well-known example of aneuploidy is found in people with Down-Syndrome, who have an extra copy of ...

"Aneuploidy -- an abnormal number of chromosomes in a cell -- is the leading genetic cause of miscarriage and congenital birth defects, including Down syndrome." Balboula and his team also ...

But the best tests of any theory are its accuracy at making experimental predictions in settings not directly related to those in which it was formulated, and its ability to explain previously ...

"Aneuploidy—an abnormal number of chromosomes in a cell—is the leading genetic cause of miscarriage and congenital birth defects, including Down syndrome." Balboula and his team also ...

Chromosomal abnormalities occur in 0.1% to 0.2% of live births, and the most common clinically significant aneuploidy among live-born infants is Down syndrome (trisomy 21). Other sonographically ...

Aneuploidy - an abnormal number of chromosomes in a cell - is the leading genetic cause of miscarriage and congenital birth defects, including Down syndrome." Ahmed Balboula, assistant professor ...

New research shows how sister cells communicate to coordinate cell death in mouse embryos, removing defective or unneeded cells in pairs.
