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.
Define base pairing rules. summarize which pairs of nucleotides are complementary (have matching shape + charge distribution), very similar to the base pairing rules in the DNA double helix, ensuring that the message from the nucleotide sequence in the gene in the DNA is copied into a corresponding nucleotide sequence in the mRNA molecule.
