Chromosomes
S phase of Interphase
The tightly coiled structure that produces sperm is called the seminiferous tubules. These tubules are located within the testes, the male reproductive organs.
seminiferous tubules
Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.Chromosomes are made up of chromatin, tangled DNA networks, that are 'super-coiled' and large enough to be seen by a microscope.
amylose (coiled unbranched) and amylopectin (Branched)
DNA molecules are arranged as a tightly coiled helix. (:

Epididymis: one of a pair of long, tightly coiled tubes on top of each testis
Chromosomes are tightly coiled structures of DNA (and proteins).
the spindle fibers disassemble, and the chromosomes return to a less tightly coiled
it's pahophase
