Nucleic Acid Function
DNA Replication, Transcription & Translation
When the DNA molecule is inactive, the bases are linked by these hydrogen bonds and the molecule is in its spiral-shaped state. When DNA is being used—either being copied (a process called replication) or being employed to build proteins (involving the processes of transcription and translation)—the DNA molecule must be opened up, essentially “unzipped” between the bases.
Article Summary: Nucleic acids, DNA and RNA, are the vital genetic blueprints for and builders of cellular proteins. Here is how DNA is copied and proteins are built.

The bases found in nucleic acids include the double-ring purine bases Adenine and Guanine the single-ring, smaller pyrimidine bases of Cytosine, Uracil and Thymine.
