Exam 3 (HW 10) Questions and
Answers Updated 2026
D)transfer RNAs and small nuclear RNAs. - AnswerIn eukaryotic species, three separate RNA
polymerases transcribe different categories of genes. RNA polymerase III is known to primarily
transcribe;
A)messenger RNAs.
B)protein-encoding genes.
C)most ribosomal RNAs.
D)transfer RNAs and small nuclear RNAs.
E)genes responsible for DNA replication.
D) Rho-independent (intrinsic) terminators form a hairpin loop/stem loop in the RNA, followed by a
series of uracils; rho-dependent terminators require a rut sequence. - AnswerWhat are the two basic
types of terminators found in bacterial cells and what is the structure for each type?
A) Rho-independent (intrinsic) terminators require a rut sequence.; rho-dependent terminators form
a hairpin loop/stem loop in the RNA, followed by a series of uracils.
B) Rho-independent (intrinsic) terminators require a rut sequence; rho-dependent terminators form
a hairpin loop/stem loop in the RNA, followed by a series of cytosines.
C) Rho-independent (intrinsic) terminators form a hairpin loop/stem loop in the RNA, followed by a
series of cytosines; rho-dependent terminators require a rut sequence.structure.
D) Rho-independent (intrinsic) terminators form a hairpin loop/stem loop in the RNA, followed by a
series of uracils; rho-dependent terminators require a rut sequence.
A) prokaryotic transcription occurs in the cytoplasm, while eukaryotic transcription occurs in the
nucleus
C) eukaryotic transcripts are processed, while prokaryotic transcripts are translated while
transcription is still occurring
, D)prokaryotes have sigma factors for specificity of binding whereas eukaryotes have multiple general
transcription factors - AnswerWhich of the following key differences between prokaryotic and
eukaryotic transcription are TRUE? Check all that apply.
A) prokaryotic transcription occurs in the cytoplasm, while eukaryotic transcription occurs in the
nucleus
B) eukaryotic transcription is carried out by 1 RNA polymerase, while prokaryotic transcription is
carried out by 3 different RNA polymerases
C) eukaryotic transcripts are processed, while prokaryotic transcripts are translated while
transcription is still occurring
D)prokaryotes have sigma factors for specificity of binding whereas eukaryotes have multiple general
transcription factors
E) prokaryotes have to worry about unpackaging the DNA for transcription, while eukaryotes have
almost naked DNA not bound up by nucleosomes
E) Capping, splicing, addition of a poly A tail - AnswerWhat are the three processes in post-
transcriptional processes that must be completed before transcripts can be translated in eukaryotes?
A) Binding of snRNPs, addition of a poly A tail, splicing of introns
B)Binding of snRNPs, transporting, synthesizing of ribose
C) Capping, transporting, synthesizing of ribose
D) Binding of snRNPs, capping, splicing
E) Capping, splicing, addition of a poly A tail
B) is called linkage disequilibrium. - AnswerThe association of certain alleles with each other, so that
these combinations occur more frequently in a population than expected through random
assortment
