How to Choose the Right Mate
Genetically programmed recombination plays an important role in differentiation, antigenic variation, and evolution in many systems. Mating-type switching is an example of programmed recombination, and studies of both the budding yeast [1] and fission yeast [2] have provided a wealth of knowledge on how epigenetic and genetic machineries interact with each other to control this process. Fission...

The results complete our insight into earlier erroneous conclusions on the ability of certain bacteria to use arsenate instead of phosphate.
