Coiled up DNA, combined with protein histone, forms chromosomes.
yes it is
DNA is coiled around histones to make a "10nm string." This is then further compacted in a either a solenoid or zig zag fashion to form a "30nm string." This is then further compacted, eventually leading to chromosomes.
the highly coiled form of DNA is a double helix.

Chromosomes
Maurice Wilkins & Rosalind Franklin : they developed a high quality x-ray diffraction photographs of strands of DNA. these photographs suggested that the DNA molecule resembled a tightly coiled helix and and was composed of 2 or 3 chains of nucleotides .
DNA is located in chromosomes inside the nucleus of a cell. This is called nuclear DNA. An organism's complete set of nuclear DNA is called its genome. Humans have a small amount of DNA found in structures mitochondria, which generates the energy the cell needs to function properly.
chromotid
DNA is the molecule that genes are made of. Chromosomes are the (arbitrary) clumping that genes form in cells.
DNA replication
The most tightly-coiled form of DNA is a chromosome.
the DNA tightly coils around a group of bead like proteins called histones
DNA molecules are arranged as a tightly coiled helix. (:
Chromosomes are tightly coiled structures of DNA (and proteins).

S phase of Interphase
The "beads on a string" are called nucleosomes.
When DNA is in its coiled up form, it is called a chromosome. These exist in the nucleus of each cell.
Eukaryotic chromosomes contain both DNA and protein tightly packed together to form Chromatin. Chromatin consists of DNA tightly coiled around histones. DNA and histone molecules form nucleosomes. These are all part of the structure of chromosomes.
Chromatin is tightly coiled and wrapped around proteins called histones to form structures called chromosomes
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.
