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.
1 In DNA, Adenine binds to Thymine. 2  In RNA, Adenine binds to Uracil. 3  These hydrogen-bond interactions between nucleotides C-G and A-T or A-U are referred to as base-pairing or complementary base-pairing. 4  Base-pairing holds the double-stranded DNA molecule together.
