What does it do for our body?
Necleic acids are the basic instructions for everything that goes on in the body. Nucleic acids are the code that that body runs on. Without nucleic acids life would not be possible.
How is it used?
DNA and rna are read by the body through 3 codons. These codons act like letters and when put into groups of three act like words. The cell uses these sentences to create proteins.
Where is it?
Nucleic acid is found in the center of the nucleus.
