EOG8MWBNP	GO:0000785	1/13	chromatin	cellular_component	"The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome." [GOC:elh, PMID:20404130]
EOG8MWBNP	GO:0035092	1/13	sperm chromatin condensation	biological_process	"The progressive compaction of the spermatid chromatin so that it reaches a level of condensation that is not compatible with nuclear activities such as transcription or DNA replication." [GOC:bf, PMID:11735001]
EOG8MWBNP	GO:0036126	1/13	sperm flagellum	cellular_component	"A microtubule-based flagellum (or cilium) that is part of a sperm, a mature male germ cell that develops from a spermatid." [GOC:cilia, GOC:sart, PMID:8441407]
EOG8MWBNP	GO:0005634	1/13	nucleus	cellular_component	"A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent." [GOC:go_curators]
