Histone proteins serve as spools around which DNA wraps, forming nucleosomes. The DNA is wound around these protein spools multiple times to create a more compact structure known as chromatin. Further compaction of chromatin leads to the formation of chromosomes.

What is the simplest level of packing of the eukaryotic chromosome?
The simplest level of packing of the eukaryotic chromosome is the wrapping of DNA around histone proteins to form nucleosomes. Nucleosomes consist of DNA wrapped around a core of histone proteins, which serves as the basic unit of chromatin packaging in eukaryotic cells.
What is the fundamental repeating unit of organization in a eukaryotic chromosome?
The fundamental repeating unit of organization in a eukaryotic chromosome is the nucleosome. A nucleosome consists of DNA wrapped around a core of histone proteins. Multiple nucleosomes are connected by linker DNA to form chromatin fibers.
What is histone core?
The histone core is a protein complex around which DNA is wrapped to form nucleosomes in chromatin. It consists of an octamer of four core histone proteins (H2A, H2B, H3, and H4) that help to package and organize DNA in the cell nucleus.
Eukaryotic chromosomes contain both DNA and protein tightly packed together to form a substance called?
The complex of both histone and non-histone chromosomal proteins and DNA is known as chromatin.
In order for the DNA molecule to get short and fat to become a chromosome it must first wrap around small molecules called?
histones. These histone proteins help condense and organize the DNA into a compact structure by forming nucleosomes, which are the basic units of chromatin.
What is the simplest level of packing of the eukaryotic chromosome?
The simplest level of packing of the eukaryotic chromosome is the wrapping of DNA around histone proteins to form nucleosomes. Nucleosomes consist of DNA wrapped around a core of histone proteins, which serves as the basic unit of chromatin packaging in eukaryotic cells.
In eukaryotic cells each chromosome has?
In eukaryotic cells, each chromosome has one or more DNA molecules, which are tightly coiled around proteins called histones. These DNA-histone complexes form chromatin fibers, which condense further to create distinct chromosomes during cell division.
What is a chromosome made up of?
A chromosome is made up of DNA, histone proteins, and other associated proteins. The DNA is organized and packaged around the histone proteins to form a complex structure that carries genetic information. Each chromosome contains specific genes that determine an individual's traits and characteristics.
What is the fundamental repeating unit of organization in a eukaryotic chromosome?
The fundamental repeating unit of organization in a eukaryotic chromosome is the nucleosome. A nucleosome consists of DNA wrapped around a core of histone proteins. Multiple nucleosomes are connected by linker DNA to form chromatin fibers.
What consists of DNA and protein condenses to form chromosomes?
DNA and proteins, specifically histones, condense together to form chromosomes. DNA molecules wrap around histone proteins to create nucleosomes, which then coil and pack together tightly to form the condensed structure of a chromosome.
What kind of protein forms the support for the DNA in a chromosome?
Histone proteins form the support structure for the DNA in a chromosome. They help package and organize the long DNA strand into a more compact structure, which is necessary for proper cell division and gene expression.
What is the section of DNA called that has eight associated histone proteins?
The section of DNA with eight associated histone proteins is called a nucleosome. Nucleosomes are the basic unit of DNA packaging in eukaryotic cells, where DNA is wrapped around a core of histone proteins to form a chromatin structure.
What are functions of chromosome?
A chromosome is very tightly packed DNA. DNA stores the information that is used to synthesize proteins. Thus the entire makeup and organization of an organism relies on the information stored in the chromosomes. DNA becomes wrapped around proteins known as histones. 8 histones form a structure known as a nucleosome. Multiple nucleosomes condense together with the addition of another histone, H1 to form a 30 nanometer fiber. Scaffolding proteins further pack the 30 nanometer fiber into a chromosome.
What include the DNA molecules chromosomes nucleosomes histones?
A choromosome is made up of DNA strand and the folding of DNA to form a choromosome is done with the help of histone proteins so DNA with histone forms nucleosome which give rise to a structure known as chromosome
What composed of a granular cluster of eight proteins?
The composed of a granular cluster of eight proteins is a histone octamer. This structure consists of two sets of four core histone proteins (H2A, H2B, H3, and H4) that form a cluster around which DNA is wrapped to create a nucleosome.
What is histone core?
The histone core is a protein complex around which DNA is wrapped to form nucleosomes in chromatin. It consists of an octamer of four core histone proteins (H2A, H2B, H3, and H4) that help to package and organize DNA in the cell nucleus.
Is it true or false The length of DNA ina chromosome may be as much as 10000 times as long as the chromosome itself?
True. The DNA in a chromosome is tightly packaged and condensed, so the actual length of DNA in a chromosome can be much longer than the physical length of the chromosome itself. This is possible due to the coiling and folding of DNA around histone proteins to form chromatin, allowing for a significant amount of genetic material to be compacted within a small space.
