Enzymes that break down DNA catalyze the hydrolysis of thecovalent bonds that join nucleotides together. What wouldhappen to DNA molecules treated with these enzymes?(A) The two strands of the double helix would separate.(B) The phosphodiester linkages of the polynucleotidebackbone would be broken.(C) The pyrimidines would be separated from the deoxyribosesugars.(D) All bases would be separated from the deoxyribose sugars.
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.
The following diagram represents a DNA molecule that is undergoing replication. Draw in the strands of newly synthesized DNA and identify (a) the polarity of the newly synthesized strands, (b) the leading and lagging strands, (c) Okazaki fragments, and (d) RNA primers.
