Question
Chapter 25, Problem 7PP
Interpretation Introduction
Interpretation:
The structural formula showing hydrogen bonds between lactam form of guanine and thymine are to be written and further indicate the consequences it might have onto the complementary strand during the next replication cycle.
Concept Introduction:
Normally, in DNA, guanine occurs in the lactam form and pairs with cytosine by forming three hydrogen bonds. When guanine tautomerizes to lactam form, it pairs with thymine instead. This mispairing then passes on to the daughter DNA (deoxyribonucleic acid) formed during replication and hence, brings about permanent changes called mutations.

Draw the formula of each of the following tripeptides:
(a)Aspartic acid- histidine- tryptophan
(b) Glycine- cysteine with the charges that exist in the cell fluid
(c) Lysine-phenylalanine- threonine
(d)Alanine- leucine- valine with the charges that exist in fluid
In the discussion of poly(ether ether ketone), or PEEK,
in Section 26.6a.2, we observed that the addition of
a tert-butyl group to the aromatic ring increases the
solubility of a PEEK in organic solvents. However,
when researchers added a second tert-butyl group,
as shown here, they found that the solubility of the
PEEK decreased. Explain this observation.
A PEEK with two tert-butyl groups per repeating unit
(a) Why can’t two purine bases (A and G) form a base pair and hydrogen bond to each other on two strands of DNA in the double helix? (b) Why is hydrogen bonding between guanine and cytosine more favorable than hydrogen bonding between guanine and thymine?
