Merotelic kinetochore (single kinetochore attaches to microtubules from two spindle poles) has been proposed to be the major mechanism underlying the spontaneous formation of lagging chromosomes, ...

Sex chromosomes are unusually labile systems, with frequent shifts between male and female heterogamety and with a large variety in the precise number and types of chromosomes. The lability is further ...

A hallmark of cancerous cells is an abnormal number of chromosomes or chromosome arms, known as aneuploidy. While aneuploidy ...

Cincinnati Children's Hospital Medical Center study links regions of two chromosomes to susceptibility for a type of autism characterized by regression in development. CINCINNATI -- A new Cincinnati ...

New research shows that the male X chromosome is silenced in some types of cancer. Researchers evaluated how a certain gene affects the male X chromosome in cancer cells. Experts explain why these new ...

A new study has found that the X chromosome, of which one copy is typically inactivated in XX female cells, can also be inactivated in some male cancers. The study is published in Cell Systems. The X ...

We previously reported suggestive linkage between type 2 diabetes and markers in a region on chromosome 20q using data from a collection of 29 Caucasian families in which type 2 diabetes with ...

In recent years, scientists have begun to learn more about a type of mutation called chromothripsis that was discovered a few years ago in chronic lymphocytic leukemia. The term chromothripsis ...

This figure demonstrates the organization process of a chromosome. Chromosome Droplets are formed during this process and act as a basic packaging unit of the chromosome. Their structures are ...

In this activity, students review how human physical traits, such as eye color, are determined by specific segments of genes. Students will use basic crafts materials to build a simplified model of a ...
