Chromatin
Nucleus.
Histones are the basic proteins that form the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes. These proteins help to package and condense the DNA within the cell nucleus.
The spiral shape of a coiled protein is called an alpha helix. This secondary structure is formed by hydrogen bonds between amino acids in the protein chain, resulting in a tightly wound helical structure.
The rod-shaped structure of tightly coiled DNA found in the cell nucleus of plants and animals is called a chromosome.
The protein around which chromosomal DNA is coiled is called histones. Histones help in organizing DNA into structural units called nucleosomes, which then further coil and condense to form chromatin fibers.

Loosely coiled DNA refers to chromatin, which is the complex of DNA and proteins that makes up a chromosome in the cell. When the DNA is loosely coiled, it allows for easier access to the genetic information for processes such as gene expression and replication. This relaxed state is important for regulating gene activity and enabling various cellular functions.
A nematocyst is a coiled protein strands that have barbs tipped with poison. It is a capsule within a specialized cells.
Coiled up DNA, combined with protein histone, forms chromosomes.
Chromatin
They are inside nucleus.They are coiled only when dividing.
chromatin is coiled threads containing the genetic code

The parts of the nucleus that carries genetic information are the Chromosomes. A chromosome is an organized structure of DNA and protein found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.
