,Heat can be used to separate two strands of double-stranded DNA, with the least

amount of heat necessary to separate strands with the fewest and weakest

bonds holding them together. Consider the following double-stranded DNA

sequences that each consist of 10 bp. Which sequence will likely require the

least amount of heat for separation?

(A) CGTGCCATTG

GCACGGTAAC



(B) GCCTCTAGGC

CGGAGATCCG



(C) AATGCTTATA

TTACGAATAT



(D) GCTATACTAG

CGATATGATC - ANSWER (C) AATGCTTATA

TTACGAATAT



Which of the following scientists is credited with the discovery of transposable

elements (TE)?

(a) James Watson

(b) Rosalind Frankin

(c) Erwin Chargaff

(d) Barbara McClintock

(e) Francis Crick - ANSWER (d) Barbara McClintock



The Ames test is used to determine



(a) whether a substance is a mutagen

,(b) whether a substance is a nucleic acid

(c) whether a substance contains amino acids

(d) whether a substance is a polypeptide - ANSWER (a) whether a substance is a mutagen



In eukaryotes, which of the following is a role for RNA polymerase II?



(a) RNA polymerase II moves along the coding strand of DNA and uses it to

provide information to synthesize a complementary strand of DNA during

replication.

(b) RNA polymerase II moves along the template strand of DNA and uses it to

provide information to synthesize a complementary strand of DNA during

replication.

(c) RNA polymerase II moves along the coding strand of DNA and uses it so

provide information to synthesize a complementary strand of mRNA during

transcription.

(d) RNA polymerase II moves along the template strand of DNA and uses it to

provide information to synthesize a complementary strand of mRNA during

transcription. - ANSWER (d) RNA polymerase II moves along the template strand of DNA and uses it to

provide information to synthesize a complementary strand of mRNA during

transcription.



Assume you have recently isolated double-stranded DNA and quantified the

amount of each nucleotide that is present in the sample. You find that there is

20% adenine (A). Using this information, you think you can determine the

amount of cytosine (C) residues that are present in the sample. After

considering that, you conclude that



(a) C = 15%

(b) C = 20%

, (c) C = 30%

(d) C = 60%

(e) Based on the information provided, you cannot make a conclusion about the

amount of C that is present. - ANSWER (c) C = 30%



in eukaryotes, the first version on the transcript that is produced is called pre-mRNA. It is then processed
by the removal of ____ sequences, the addition of a polyA tail and the addition of a 5' cap. this produces
the final mature mRNA. - ANSWER intron



The addition of 1 or 2 nucleotides into a DNA sequence causes a __________________

mutation in the corresponding polypeptide sequence that it encodes. - ANSWER frameshift



The _____________________________ is the region at the end of a linear chromosome

that requires a special system for replication. - ANSWER telomere



6. The chromosome theory of inheritance first proposed that the chromosomes

carry the genetic information. Even then, it was known that chromosomes

consist of ________________________________________.



(a) Large amounts of DNA and RNA and small amounts of protein

(b) Large amounts of DNA and RNA but no protein

(c) Large amounts of DNA and protein and small amounts of RNA

(d) Large amounts of DNA but no protein and no RNA - ANSWER (c) Large amounts of DNA and protein
and small amounts of RNA



7. During replication, the enzyme/protein that helps separate two strands of DNA

as the replication fork moves in either direction is called

(a) endonuclease

(b) openase

(c) primase
