What else can I help you with?
What do prokaryotes and eukaryotes have in commmon?
DNA, proteins, plasma membrane
How is DNA packaged in prokaryotes?
Not really " packaged " in the sense that eukaryotes package their DNA. Prokaryote DNA is diffuse throughout the cell and is in rings. Also other smaller rings, called plasmids, are also part of prokaryote genetic complements.
Do eukaryotes have histones?
Yes, eukaryotes have histones, which are proteins that help in packaging and organizing DNA within the nucleus. Histones associate with DNA to form nucleosomes, the basic repeating unit of chromatin.
What is the name of the family of DNA binding proteins that function to package DNA into chromatin?
histones are the proteins that compact and order DNA into subunits in the first step of the making of chromatin
How is the DNA in prokaryotes different from from the DNA in a eukaryotes?
dna in eukaryotes is located in the nucleus
What is histon?
A Histone Core is a group of Histone Proteins, mainly used in eukaryotes to package DNA strands into Nucleosomes. (Think of it like a spool for the DNA to wrap around, to be easily stored on a shelf)

What is composed of DNA and proteins?
Chromatin is composed of DNA and histone proteins. Histone proteins help package and condense DNA into a complex structure that fits within the nucleus of a cell.
How is the DNA in a prokaryote different from the DNA in a eukaryotes?
DNA in prokaryotic cells is usually circular while DNA in eukaryotes is usually linear. DNA in prokaryotes usually has fewer portions that dont code for something while eukaryotes usually have quite a bit of DNA sections that dont code for anything. The number of actual base pairs (the units that makeup DNA) that makeup eukaryotes is usually quite a bit more than the number in prokaryotic DNA.

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.
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 proteins are associated with DNA in a cell?
Histones are the main proteins associated with DNA in a cell. These proteins help to package and organize DNA into chromatin, which plays a role in gene regulation and overall genome structure. Other DNA-binding proteins, such as transcription factors, also interact with specific regions of DNA to regulate gene expression.
