The "beads on a string" are called nucleosomes.
Histones

Chromatin
chromosomes. The DNA is genes that are tightly wrapped around proteins. The proteins are histones.
Yes - chromosomes are composed of compact DNA which is wound around proteins (called histones).
Histones and other associated proteins
Eukaryotic cells have a double membrane, surrounding the nucleus, the organelle that contains several chromosomes. The prokaryote chromosomes are dispersed within the cell and is not enclosed by a separate membrane
Chromosomes - structures composed of DNA and proteins found in the nucleus of eukaryotic cells. Chromosomes carry the genetic material. Chromosomes - structures composed of DNA and proteins found in the nucleus of eukaryotic cells. Chromosomes carry the genetic material.

Histones and other associated proteins
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.
The nucleosome is the basic unit that organizes the structure of an eukaryotic chromosome. The nucleosome is DNA wrapped around histone proteins which allows the DNA to condense into chromosomes.
All nuclear DNA in eukaryotes is linear DNA. Eukaryotic chromosomes, such as those in human cells, are linear DNA molecules spooled around support proteins called histones.
DNA wraps around proteins that help organize and condense it.
