S phase of Interphase
Sperm cells are produced within tightly coiled tubes in the testicle called seminiferous tubules.
The tightly coiled structure that produces sperm is called the seminiferous tubules. These tubules are located within the testes, the male reproductive organs.
The tightly coiled structure that contains hereditary material in a cell is the chromosome. Chromosomes are composed of DNA and proteins, and they carry genetic information that determines an organism's traits.
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.
DNA molecules are arranged as a tightly coiled helix. (:

Chromosomes are tightly coiled structures of DNA (and proteins).
The tightly coiled structure that contains hereditary material in a cell is the chromosome. Chromosomes are composed of DNA and proteins, and they carry genetic information that determines an organism's traits.
The rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals is called a chromosome.
the spindle fibers disassemble, and the chromosomes return to a less tightly coiled
