HOW TO FORM NUCLEIC ACIDS
First reaction:
Nitrogen base + 5-carbon sugar
Nitrogen base + 5-carbon sugar
nucleoside
Second reaction:
Phosphoric acid + nucleoside
Phosphoric acid + nucleoside =
nucleotide
The combination of a phosphoric acid with a nucleoside produces a nucleotide, which is a
phosphate ester of a nucleoside.
The formation involves a (blank) reaction
condensation
The formation involves a condensation reaction between the
phosphoric acid and the alcohol group on carbon number 5, the –CH2OH.
Third reaction:
Nucleotide becomes nucleic acid
contain two intertwining polynucleotide strands
DNA
have only a single
