The protein histone, and attendant proteins, spool the DNA tightly around their complexes and then further wind these complexes into tighter and tighter shapes. About two meters worth of DNA per cell is held in these histone complexes.

What One of the factors allowing DNA to fit inside the nucleus of a cell is its ability to?
coil tightly around associated proteins"
What is chief role of the nucleus in a cell?
The nucleus contains the DNA, which has the instructions for the production of functional products (i.e. proteins). Therefore the main role of the nucleus is to control the functions of the cell.
The code for the synthesis of proteins is contained in?
The DNA of the cell.
What role does DNA play in an organism?
DNA is composed of four deoxyribonucleic acids. The sequence of these determines the sequence of amino acids in proteins. Proteins are essential in maintaining and multiplying cells. Additionally DNA is structured in such a way that it can be copied exactly when the cell prepares to divide.
How DNA linked to the role of ribosomes in a cell?
DNA contains the coding for proteins (which are made at the ribosomes) mRNA copies the coding from the DNA and carries it to the ribosome, where tRNA builds up the protein.
What role do proteins play in enabling the enormous amounts of DNA in the eukaryote cell to fit into the nucleus and what are the proteins called?
DNA that is not being "used" by the cell is wrapped up around proteins called histones.

What is the Role of the DNA molecule in cells?
DNA is much like the "brain" of the cell. It contains genes that produce proteins through transcription (DNA--->RNA) and translation (RNA---->protein). Proteins are what give a cell its function (i.e. turns it from a generic cell into a muscle cell). in a nutshell, it basically tells the cell what to do.

What proteins are associated with DNA in the cell?
histones are the proteins that DNA coils aroudn
What does a DNA do for a cell?
DNA has the instructions for making all of the cell's proteins. The proteins handle everything else. So in this way DNA directs all the cell's activities.

DNA controls production of?
DNA controls the production of certain proteins in the cell. Different DNA codes make different proteins. Proteins made in the cell bond together to make amino acids.
How DNA linked to the role of ribosomes in a cell?
DNA contains the coding for proteins (which are made at the ribosomes) mRNA copies the coding from the DNA and carries it to the ribosome, where tRNA builds up the protein.
What directs the production of proteins in the cell?
DNA
