∙ 13y agoEukaryotic chromosomes contain both DNA and protein, tightly packed together to form a substance called chromatin. Chromatin consists of DNA that is tightly coiled around preteins called histones. Together the DNA and histone molecules form a beadlike structure called nucleosome. Nucleosome pack with one another to form a thick fiber, which is shortened by a system of loops and coils.
Hope that helps (:

∙ 9y agoDNA is tightly packed inside itself. Each chromosome consists of one continuous thread-like molecule of DNA coiled tightly around proteins.

Where are the genes of a eukaryotic organism located?
Genes are found within the DNA code of chromosomes in both eukaryotes and prokaryotes. Chromosomes are found in the nucleus of eukaryotes.
Where is the DNA dor an organism found?
In eukaryotes, DNA is located on the chromosomes in the cell nucleus. In prokaryotes, DNA is located on a single chromosome in the cell cytoplasm.
Are chromosomes found in the nucleus of plant and animal cells?
Chromosomes as such as found only within the nucleus. The mitochondria of animal and chloroplasts of plants contain their own DNA. This DNA is present in the form of a large loop of plasmid-like structure. This is referred to as the mitochondrial genome or the chloroplast genome, depending on where it is found. However, these genomes do not have tightly packed DNA like that found in chromosomes and are not considered chromosomes.
Where are chromosomes found?

Where is the DNA in prokaryote in a eukaryote?
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.
What molecules are found in chromosomes?
DNA molecules.
Where chromosomes are in a cell?
Chromosomes are found in the nucleus of animal cells (eukaryotes). In bacteria and archaebacteria, they float freely in the organism.
Where a chromosmome is located in the cell?
In Eukaryotes (including plants and animals) - chromosomes are found in the nucleus.
How many cells does a bacterial chromosomes have and what shape are they?
I'm afraid your questions doesn't make sense. Chromosomes don't have cells- they are found in cells. Bacteria are unicellular organisms so only consist of one cell, but they are capable of having multiple chromosomes. In Eukaryotes chromosomes are found in the nucleus but bacteria are Prokaryotes. Since they do not have a nucleus, the chromosomes can be anywhere within the cell. Where it gets tricky is that bacteria can also have molecules called "Plasmids" which are DNA molecules distinct from Chromosomal DNA. Typically Plasmids are circular and Chromosomes are in an X shape, but both are made of DNA which is in the infamous double helix shape. Good luck :)
Where are the genes of a eukaryotic organism located?
Genes are found within the DNA code of chromosomes in both eukaryotes and prokaryotes. Chromosomes are found in the nucleus of eukaryotes.
Where are alleles located?
Alleles are forms of a gene, which are located in the DNA of an organism, typically found in chromosomes that reside in a nucleus (eukaryotes).
Where in a cell is DNA found?
DNA is found in the nucleus of eukaryotes or in the cytoplasm of prokaryotes. The DNA forms complex strands known as chromatin, and when dividing, chromosomes.
What is the function of the nuclear pore complex that is found in all eukaryotes?
It regulates the movement of all molecules into and out of the nucleus. That's a chop!

In eukaryotes, DNA is located on the chromosomes in the cell nucleus. In prokaryotes, DNA is located on a single chromosome in the cell cytoplasm.

How are the long DNA molecules found in eukaryotes packed into short chromosome.?
Because the DNA molecules are twisted around and around. Almost like if you start twisting a string it will curl and then curl again upon itself.
Is the tata box found on prokaryotes eukaryotes?
i think it is only in eukaryotes
