Pairing up: How chromosomes find each other

After more than a century of study, mysteries still remain about the process of meiosis -- a special type of cell division that helps insure genetic diversity in sexually-reproducing organisms. Now, researchers at Stowers ...

Nematode proteins shed light on infertility

In a new study published in the Proceedings of the National Academy of Sciences, University of Utah (the U) biologists have developed a method for illuminating the intricate interactions of the synaptonemal complex in the ...

High-end microscopy refined: ExM

The synaptonemal complex is a ladder-like cell structure that plays a major role in the development of egg and sperm cells in humans and other mammals. "The structure of this complex has hardly been changed in evolution, ...

Landmark study sheds new light on human chromosomal birth defects

Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as ...

X marks the spot: recombination in structurally distinct chromosomes

Two years ago, scientists from the Stowers Institute for Medical Research reported the 3-D structure of the synaptonemal complex in the fruit fly Drosophila melanogaster. This large protein complex is a critical player in ...
