Nucleic Acids

Nucleic Acids

Unbranched polymers composed of repeating monomers called nucleotides.

Nucleotide (Mononucleotide)

The repeating unit made up of a sugar unit, N-base, and phosphate group.

DNA Function

Responsible for storage and transmission of the genetic material.

RNA Function

Involved in the manufacture of proteins and translating genetic information.

Phosphodiester Bond

The linkage between monomers (nucleotides)
