nucleosome - "beads on a string"
30 nm condensed chromatin fiber
Sperm chromatin is an exception to the above. During spermiogenesis
, the male germ cell 's chromatin is remodelled into a more tightly packaged, compact structure. This process is associated with the cessation of t...
When formed, early round spermatids must undergo further maturational events in order to develop into spermatozoa , a process termed spermiogenesis
(also termed spermeteliosis ).
The spermatids begin to grow a tail, develop a thickened mid-piece where the mitochondria become localised and for...

The spermatids at this point are still round cells. During the process called spermiogenesis
the sperm extrude tails, repackage DNA into a head, cap the head with a lysosome-like acrosome and construct an energy transducing neck region of ...
