Setting the stage for passing on epigenetic information to the next
... chromatin based epigenetic information is retained during the development of the sperm that eventually may be passed on to the next generation. In sperm, DNA is 10- to 20-fold more tightly packed than in nuclei of regular cells. The tight packaging of DNA is mediated by protamine proteins, which are ...
