Am if you are talking about it's role it's quite obvious.
Nucleic acids:
    - take part in hereditary processes
    - code genetic information about structure of proteins occuring in the organism - especially enzymes
    - rybonucleic acids have also catalytic (enzymatic) properties
    - are responsible for variety of forms of organisms (different alleles of genes)
    - coordinate metabolism of a cell (by translating new proteins when needed)
    etc


I think you may figure out some more processes or situations in which nucleic acids are essential. Nevertheless I will try to find some more sophisticated and more detailed informations in text books or reference books.

A nucleic acid is a polymer comprising a pentose sugar, a phosphate molecule attatched to carbon 5' and an organic base attatched to carbon 1' of the sugar.

a nitrogen-containing "base" - either a pyrimidine (one ring) or purine (two rings)
a 5-carbon sugar - ribose or deoxyribose
a phosphate group equals nucleic acid
