seminiferous tubules
true
The tightly coiled structure that produces sperm is called the seminiferous tubules. These tubules are located within the testes, the male reproductive organs.
Chromosomes
S phase of Interphase
Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
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.
Epididymis: one of a pair of long, tightly coiled tubes on top of each testis
The tightly coiled structure that produces sperm is called the seminiferous tubules. These tubules are located within the testes, the male reproductive organs.

The "beads on a string" are called nucleosomes.
DNA molecules are arranged as a tightly coiled helix. (:
