chromosome

Isabella, 3, suffers a devastating genetic abnormality where the 18th chromosome appears three times, rather than twice.

US scientists believe they have discovered the genetic code that makes some people sleepwalk.

(University of Washington) Cells stabilize their machinery for forcing apart chromosomes in an amazingly simple way.

Attachments between the microtubules that tug apart the chromosomes and the connector on the chromosomes become more stable when they are placed under tension.

This tension occurs when the microtubles are properly aligned on either side of the paired chromosomes. If the alignment is incorrect, the tension is weak, and the attachment is released and fixed.

This stabilization method assures accurate separation of chromosomes.

A gene on chromosome one appears to be linked to moderate to severe persistent asthma in children (MedPage Today) -- the second such genetic locus associated with the disease.

A newly discovered gene on chromosome 17 -- an area rich with other autism-related genes -- may help explain why the disorder affects boys so much more often than girls
