How to calculate the pI - ....ANSWER...(1) determine the
highest positive charge possible
(2) list all of the pKas in order from smallest to largest
(3) start in the space before the first pKa and jump to the

pH=7 and (c) pH>9 - ....ANSWER...(a) positive

Name the monomer of nucleic acids -
....ANSWER...nucleotides


Describe the relative stability of DNA and RNA -
....ANSWER...DNA is more stable than RNA because
DNA lacks the 2' hydroxyl group; since DNA only has a 3'
hydroxyl group, the phosphodiester bonds formed are
specific and rigid; also, the C-H bond at the 2' carbon in
deoxyribose is much less reactive than the C-OH bond in
ribose
