The antibiotic puromycin kills both eukaryotic and bacterial
cells because it:
A) binds to the rRNA that catalyzes the formation of peptide
bonds and that rRNA is the same for eukaryotic and bacterial
cells
B) can directly bind to any small ribosomal subunit
C) binds to the large ribosomal subunit and large ribosomal
subunits are the same for eukaryotic and bacterial cells
D) resembles the 3ʹ end of a charged tRNA and tRNA structure is
similar in all organisms
Explain the regulation of gene expression in eukaryotic
cells.
Discuss mechanisms by which gene expression may be
altered.
How do these alterations induce cancer-causing mutations in
cell DNA?
Explain how cancer is formed.
Describe genetic changes found in cancer cells and how these
changes lead to alterations in cell behavior.
Determine whether proteome data can be utilized in genetic
disorder diagnosis.
Relate the Human Genome Project data to the analysis of cancer
genes.
Which model of categorization proposes that our representation
of a given category is organized around family resemblances, based
on the most commonly shared attributes of items from that
category?
a. Exemplar-based model
b. Classical model
c. Theory-based model
d. Prototype-based model
e. Rule-based model
Sometimes, our categories respond not simply to lists of
features, but also to causal explanations about how things work in
the world. This is a description of:
a. schemas
b. classical categorization
c. functionalism
d. theory-based...
The
promoter is an important sequence for transcription of a gene.
Which of these components binds to the promoter of a eukaryotic
gene to allow transcription to begin? Select all that are
correct.A. Ribosomal subunitsB. A start codonC. DNA polymerase enzymeD. General transcription factorsE. RNA polymerase enzyme
Which of the following is a difference between prokaryotic and
eukaryotic gene expression
Group of answer choices
1)Eukaryotes have basal transcription factors not part of the
holoenzyme
2)Eukaryotes produce an immature mRNA
3)Trancription and translation can occur simultaneously in
Prok.
4)Eukaryotics have more diverse promoters
5)All of the above
Explain how the primary transcript of a single eukaryotic gene
can produce different proteins, using Drosophila
sex-specific courting behavior as an example.
Briefly describe how genomic imprinting can be inferred from
inheritance patterns in human pedigrees.
1. The role of the repressor gene was initially described with
the aid of both single mutants and specifically constructed
partially diploid strains of E. coli.
a. List the phenotype ( Inducible, Constitutive, or
Non-inducible ) of each of the following partial diploids with
respect to the synthesis of beta-galactosidase and lactose
permease. No explanation is necessary.

42. Which of the following is not a normal property of
the eukaryotic mRNAs?
A. Most have a significant untranslated region that doesn't direct
assembly of amino acids
B. They are processed from pre mRNAS to mRNAs in the nucleus and
are exported through the nuclear pore complex
C. All of the answers are true
D. They are found in the cytoplasm
E. They are often being translated by more than one ribosome at a
time in a structure known...
