NUCLEIC ACIDS
❁
nucleic acids – large complex organic molecules
composed of carbon, oxygen, hydrogen, nitrogen, &
phosphorous
 Role/Function: Store & transmit genetic info
responsible for life
 polymers of monomers known as nucleotides
 nucleotide – unit of a nucleic acid that is
made up of a 5 carbon sugar,
phosphate group, & a
nitrogenous base
