Nebenkern

The nebenkern is a mitochondrial formation in the sperm of some insects such as Drosophila. After the completion of meiosis, spermatid mitochondria wrap around each other to form a spherical aggregate, adjacent to the nucleus.[1] The nebenkern proceeds to elongate into a double-stranded helical structure.[1][2] During flagellum elongation the nebenkern unfolds and the two derivatives (major and minor mitochondrial derivatives) elongate down the bundle of microtubules that constitute the axoneme core of the flagellum.[3]

gollark: Will anyone *notice* if computing their autocrafting job takes a few hours?
gollark: So that doesn't actually help at all with the more significant problem of dealing with the fact that this makes there be a lot of different crafting paths to try!
