Abstract
The "immortal strand" hypothesis proposes that asymmetrically dividing stem cells selectively retain chromosomes containing "old" DNA to prevent accumulation of mutations. As I describe in this Essay, such a possibility seems unlikely. An alternative explanation is that asymmetric cell divisions and cell fate are codirected by epigenetic differences between sister chromatids.Mesh:
