14.11 The Organic Chemistry of Biomolecules: Aromaticity and DNA 14.48 A strand of nucleic acid is defined by its sequence of nucleotides: A, C, T, and G. How many different sequences are possible for a nucleic acid that is 200 nucleotides long? How does that number compare to the estimated number of atoms in the universe, which is approximately 1080?

State the two criteria that governs aromaticity?
According to the general definition of aromaticity and the Hackle's 4n + pi rule, predict the aromaticity of the following compounds. Write the numbers of aromatic compounds: Aromatic compounds are:
15.4 Which of the lone pairs (if any) are participating in aromaticity? :N (a) a :N (b) (c) both (d) neither 15.4 Which of the lone pairs (if any) are participating in aromaticity? ON :N (b) U (a) Z: Z: (c) both (d) neither
