Textbook Question
Chapter 5, Problem 5TYU
Enzymes that break down DNA catalyze the hydrolysis of the covalent bonds that join
(A) The two strands of the double helix would separate.

Students have asked these similar questions
(1) Which end (5' or 3') of the molecule is here?
(2) Which enzyme is probably functioning here to deal with supercoils in the DNA?
(3) Which enzyme is probably functioning here to unwind the DNA?
(4) Which nucleic acid is probably depicted here?
(5) What are these short DNA fragments usually called?
(6) Which enzyme probably functions here to couple these two newly synthesized fragments of DNA?
(7) Is this strand the leading or lagging strand?
(8) Which end (5' or 3') of the molecule is here?
When DNA is heated sufficiently, the strands separate. The energy that it takes to separate the DNA is related to the amount of guanine and cytosine bases. Why is this so?
(A) Adenine and thymine make 3 hydrogen bonds between each other, and guanine and cytosine don't make any hydrogen bonds.
(B) Guanine and cytosine make 3 hydrogen bonds between each other, and adenine and thymine don't make any hydrogen bonds.
(C) It takes more energy to break an A-T bond than it does a G-C bond.
(D) It takes more energy to break a G-C bond than it does an A-T bond.
Which of the following is NOT a characteristic of the DNA Double Helix?
a) The two strands run in an anti-parallel fashion based on their polarity.
b) Hydrogen bonding between nucleotides holds the strands together.
c) DNA is 20 Angstrom's wide.
d) The percentage of Guanine and Thymine present in a double helix strand are always equal.
