PASS
I.This occurs in the nucleus of eukaryotic cells with DNA polymerase.
II.Transfer RNAs bind amino acids in the cytoplasm.
III.An RNA polymerase enzyme is required. - correct answer I: replication; II: translation; III:
transcription
Which of the following statements regarding RNA is false? - correct answer RNA contains the
sugar dextrose
Which of the following statements regarding the structure of DNA is false? - correct answer The
sequence of nucleotides along the length of a single DNA strand is restricted by the base-pairing
rules
If the left end of the daughter strand indicated by the arrow in the figure is being synthesized in
one continuous piece, then - correct answer the DNA at point C is being synthesized in one
continuous piece
RNA splicing involves the - correct answer removal of introns from the molecule
The coding regions of a gene are called - correct answer exons
, Which permits a single gene to code for more than one polypeptide? - correct answer
alternative RNA splicing
All of the following mechanisms are used to regulate protein production except - correct
answer DNA replication
What is the basis for the difference in how the leading and lagging strands of DNA molecules are
synthesized? - correct answer DNA polymerase can join new nucleotides only to the 3' end of a
pre-existing strand, and the strands are antiparallel
The elongation of the leading strand during DNA synthesis ________. - correct answer depends
on the action of DNA polymerase
A student isolates, purifies, and combines in a test tube a variety of molecules needed for DNA
replication. When she adds some DNA to the mixture, replication occurs, but each DNA
molecule consists of a normal strand paired with numerous segments of DNA a few hundred
nucleotides long. What has she probably left out of the mixture? - correct answer DNA ligase
The anticodon of a particular tRNA molecule is ________. - correct answer complementary to
the corresponding mRNA codon
How do the leading and the lagging strands differ? - correct answer The leading strand is
synthesized in the same direction as the movement of the replication fork, whereas the lagging
strand is synthesized in the opposite direction.
What enzyme compensates for replication-associated shortening of linear chromosomes? -
correct answer telomerase
