What else can I help you with?
DNA in the nucleus is found in structures called .?
chromosomes
How are prokaryotic and eukaryotic alike and diffrent?
Prokaryotic cells have no nuclei and eukaryotic cells have a true nuclei. prokaryotic DNA is circular where eukaryotic DNA is linear.
Eukaryotic dna molecules have?
Eukaryotic DNA has histone proteins and a level of organization that prokaryotic DNA lacks.
How is protein organized in a chromosome?
Chromosomes are mostly DNA not proteins, but there are small proteins that "package" and protect the DNA. These proteins are somewhat different in prokaryotes and eukaryotes:Prokaryotes do not possess nuclei. Instead, their DNA is organized into a structure called the nucleoid. This structure is, however, dynamic and is maintained and remodeled by the actions of a range of histone-like proteins, which associate with the bacterial chromosome. In archaea, the DNA in chromosomes is even more organized, with the DNA packaged within structures similar to eukaryotic nucleosomes.In the nuclear chromosomes of eukaryotes, the uncondensed DNA exists in a semi-ordered structure, where it is wrapped around histones (structural proteins), forming a composite material called chromatin.
What has a single nucleus in each cell?
A eukaryotic organism has a single nucleus in each of its cells. Examples of eukaryotic organisms include animals, plants, and fungi. Each cell's nucleus contains the genetic material, such as DNA, that controls the cell's activities.

To help with biology homework what are histones?
Histones are proteins found in eukaryotic cell nuclei. They are high in alkaline. Histones package and order the DNA into units that are called nucleosomes.
DNA that is spread out in a non dividing cell is called?
Chromatin. It consists of DNA wrapped around proteins called histones and is found in the nuclei of eukaryotic cells.
Eukaryotic chromosomes consist of this and DNA?
Eukaryotic chromosomes consist of histone proteins and DNA. The histone proteins help to package and organize the DNA into a compact structure, called chromatin, which allows for efficient storage and regulation of genetic material.
What does chromatin consist of?
Chromatin consists of DNA wrapped around histone proteins. These histone proteins help condense the DNA into a more compact structure, which is necessary for packaging and regulating gene expression within the cell.
DNA is only found in the?
DNA is found in the nucleus of eukaryotic cells and in the nucleoid region of prokaryotic cells. It is the genetic material that carries the instructions for the development, functioning, growth, and reproduction of all living organisms.
What basic protein forms the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes?
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.
Is DNA present in both prokaryotic cells and eukaryotic cells?
Yes, DNA is present in both prokaryotic and eukaryotic cells. In prokaryotic cells, DNA is found in a circular form in the nucleoid region, while in eukaryotic cells, DNA is located in the nucleus and organized into linear chromosomes.
Where and in what form is eukaryotic DNA found?
DNA is stored in threadlike, tangled structures called chromatin inside the nucleus of a eukaryotic cell. During mitosis, chromatin changes into structures called chromosomes. Each time the cell divides, the genetic information carried by the chromosomes is passed to the two newly formed cells, where it is stored as DNA in their nuclei.
What is the major function of a histone protein?
Histone proteins act as spools around which DNA is wound, helping to package and condense the DNA into chromatin. They also play a role in regulating gene expression by controlling access to DNA for transcription factors and other proteins.
