abstract：:The completion of spermiogenesis requires condensation of the haploid spermatid genome. This task is accomplished in a gradual and relentless manner by first erasing the nucleosomal organization of chromatin while the DNA is protected by transient nuclear proteins TP1 and TP2. Then, the more permanent protamines come ...
