Where would we be without meiosis and recombination? A new article describes how proteins called SUMO and ubiquitin and molecular machines called proteasomes play a crucial role in DNA recombination ...

Meiosis -- the pairing and recombination of chromosomes, followed by segregation of half to each egg or sperm cell -- is a major crossroads in all organisms reproducing sexually. Yet, how the cell ...

How is the same process responsible for genetic recombination and diversity also the cause of aneuploidy? Understanding the steps of meiosis is essential to learning how errors occur.

Where would we be without meiosis and recombination? For a start, none of us sexually reproducing organisms would be here, because that's how sperm and eggs are made. And when meiosis doesn't work ...
