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.
In the rules of DNA base pairing, cytosine always pairs with guanine, and adenine always pairs with thymine. The complementary shape between the two bases that form a pair allows for them to form hydrogen bonds.
