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.
A base pair is made of two nucleotides. The nucleotides, located on opposite strands of DNA or RNA, are drawn to each other in a hydrogen bond. These bonds are what hold the strand together in a double helix formation. The double structure is a redundancy that acts as a backup system to store genetic information. Base pairs facilitate transcription, which is the process whereby genetic information encoded in DNA is transferred to RNA. The information is carried in only one of the two strands of DNA, which is called the coding strand.
