Therapeutically useful stem cell derivatives in need of stability
Human stem cells capable of giving rise to any fetal or adult cell type are known as pluripotent stem cells. It is hoped that such cells, the most well known being human embryonic stem cells (hESCs), can be used to generate ...

A 'jumping gene's' preferred targets may influence genome evolution
The human genome shares several peculiarities with the DNA of just about every other plant and animal. Our genetic blueprint contains numerous entities known as transposons, or "jumping genes," which have the ability to move ...

How yeast chromosomes avoid the bad breaks
The human genome is peppered with repeated DNA elements that can vary from a few to thousands of consecutive copies of the same sequence. During meiosis—the cell division that produces sperm and eggs—repetitive ...

New light shed on cell division
Genes control everything from eye color to disease susceptibility, and inheritance - the passing of the genes from generation to generation after they have been duplicated - depends on centromeres. Located in the little pinched ...

Study suggests rare genetic variants most likely to influence disease
New genomic analyses suggest that the most common genetic variants in the human genome aren't the ones most likely causing disease. Rare genetic variants, the type found most often in functional areas of human DNA, are more ...

Genetic alteration linked with disorders of sex determination
A variety of genetic factors are involved in sex determination. If something goes wrong with one of these factors, people who have a chromosome set that predicts they will be of one sex may develop as the other sex or have ...
