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 cell's nuclear genome is contained within the genes that are located inside of the chromosomes. Chromosomes are thread like structures and are located inside of the nucleus in animal and plant cells.
Chromosomes are formed from long strands of DNA that are tightly coiled and packaged with proteins called histones. This coiling and packaging help to condense the DNA in order to fit within the cell nucleus and ensure proper organization during cell division.
The nucleus hangs by cytoplasmic strands in a spirogyra cell.
This is called chromatin. Chromatin is the complex of DNA and proteins that forms chromosomes. The coiling and folding of DNA into chromatin helps condense the genetic material to fit within the nucleus of a cell.
A nematocyst is a coiled protein strands that have barbs tipped with poison. It is a capsule within a specialized cells.
Thin long strands of DNA that are coiled, folded, and twisted into condensed structures are called chromosomes. Chromosomes contain genes that carry the instructions for inherited traits and are organized within the nucleus of a cell. During cell division, chromosomes are visible as distinct entities under a microscope.
Sperm cells are produced within tightly coiled tubes in the testicle called seminiferous tubules.
The DNA in each chromosome is longer than the diameter of an animal cell. Chromosomes are necessary to package and organize the long strands of DNA within the cell's nucleus. The DNA in a typical animal cell is tightly coiled and packaged to fit within the nucleus, which is much smaller than the length of the DNA in its extended form.
When the DNA in a cell is uncoiled and spread throughout the nucleus, it is called chromatin. Chromatin consists of DNA and associated proteins that help organize and regulate gene expression within the cell.
Pores
no its form from chromatin consists of long strands of material located within the nuclear membrane. when a cell is going to divide the chromatin rearranges and condenses into orderly strands called chromosomes ^_^ and there is 23 pairs of chromosomes in human cells cool huh:) I hope this helps;) peace
Tangled strands of DNA are in Prokaryotic cells. This is because the DNA is free floating. The proteins are most likely tangled in the protein molecules.
You are talking about chromosomes, which are made of DNA (deoxyribonucleic acid). However the chromosomes are only "strands" in eukaryotic cells, in prokaryotic cells the chromosome is a "ring" instead and there are typically several additional much smaller DNA "rings" called plasmids that contain genes that are not part of the chromosome.

The chromonemata is an individual coiled chromosome thread. The chromonemata is the coiled mass of threads visible within the nucleus at the beginning of cell division. During cell division, it remains relatively uncoiled during early prophase but assumes a more spiral shape during metaphase.
