Nucleus Nucleolus Cytoplasm The control center of the cell and dictates what all of the other organelles do. Stores the DNA in eukaryotes.Dark spherical body found in the nucleus; makes the ribosomes. A jelly-like material that surrounds the cell organelles.ucleus Nucleolus Cytoplasm The control center of the cell and dictates what all of the other organelles do. Stores the DNA in eukaryotes.
The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA, and RNA polymerase transcribes DNA into RNA.
The rule of base pairing helps explain how DNA is replicated prior to cell division. Enzymes unzip the DNA by breaking the hydrogen bonds between the base pairs.The unpaired bases are now free to bind with other nucleotides with the appropriate complementary bases.he rule of base pairing helps explain how DNA is replicated prior to cell division.
