two-semester series, but with greater emphasis on mathematical and quantitative analysis. Students
wishing to pursue this option should consult with faculty.
Instructors: Woodson, Bowman, Brand
Spring, 3 hours

and discussion of the current scientific literature. Topics include protein trafficking, membrane dynamics,
cytoskeleton, signal transduction, cell cycle control, extracellular matrix, and the integration of these
processes in cells of the immune system.
Open to graduate students and advanced undergraduates by permission of the instructor.
Fall, 3 hours
020.699 Responsible Conduct in Research (INTERSESSION)
The Johns Hopkins Departments of Biology, Biophysics, Chemistry and Carnegie Institution are committed
to promoting the highest ethical standards amoun our administration, faculty members, and students.
Therefore, all trainees and training faculty are required to attend the discussions series, Responsible
Conduct of Research. The two week series meets for 6 two hour sessions and will be offered every January.
Graduate students must attend the discussion series during their first year of study. Science has come
under increased scrutiny and scientific misconduct has become a public issue regularly addressed in the media.
Against the background of public skepticism, each university must make a visible commitment to responsible
conduct of research. We believe that this is best accomplished by case-based discussions involving both
trainees and faculty who are active investigators. In addition to general information, such as
Honor in Science, participants will be expected to read related handouts sent to them before
each session. Copies of the material contained in the suggested reading list will also be available.
Through the use of pre/post testing and presentation evaluations, the course will respond to the specific
needs of trainees and faculty.
020.606 Molecular Evolution
A history of life on earth has been recorded in the DNA of organisms that live today.
But what language is it and how can we read that history? This course introduces basic principles
of molecular evolution plus a wide array of methodologies used to interpret molecular sequence data.
Many interesting studies of gene and genome evolution will be covered as examples of this burgeoning
area of research. This fun and popular course now includes computer labs that will enable students
to obtain first-hand experience in this exciting field of research.

underlying neuronal morphology, development and function. The proper functioning of the
nervous system relies on the establishment of precise neuronal circuits through a developmental
program including proliferation, neuronal migration, axonal growth and neuronal survival.
This course pertains to the extracellular cues and downstream neuronal signaling pathways
that coordinate these key events during neuronal development. The course will also cover
the role of aberrant signaling mechanisms in neuronal degeneration and disease.

of stem cells? How do stem cells maintain their identities? What are the mechanisms underlying stem cell
differentiation and reprogramming? What are the therapeutic applications of stem cells? The student
seminar will be based on selected literatures by the faculty. A summary mini-review paper is required

020.638 Regulation and Mechanisms of the Cell Cycle
The great progress in eukaryotic cell cycle research in the past decade was made possible by a unique
synergism between different modern biological approaches (genetic, cell biological, biochemical,
and developmental). These approaches will be highlighted in this course. We will cover the mechanisms
the cell employs to carry out its duplication cycle, such as DNA replication, mitotic spindle function,
and cytokinesis, as well as the regulatory mechanisms that govern these processes. The relationship
of cell cycle biology to the cancer problem will receive special attention.
Prerequisites: 020.305, 020.306, and 020.330, or the equivalent.

020.640 Epigenetics & Chromosome Dynamics
It has become finally recognized that the primary structure of the DNA is not the sole and absolute determinant
of the phenotype of an organism. Much depends on the modulations of the primary information by time and tissue
specific enzymatic modifications of this information and the result is the epigenetic information potential within
the nucleus. This potential is dynamic; it can be “written and re-written” in the life-trajectory of a cell.
We will examine the various process and states of genome epigenetics, from simple genes to whole chromosomes,
chromosomal subsets and even the whole nucleus. This graduate level course will consist of few special overview
lectures given by the instructors and the rest will be student presentations. The topics will be selected by the
faculty but we will also consider the inclusion of special and timely topics suggested by the students.
The duration of each session will be 90 minutes. Upper level undergraduates may register with signature of the instructors.
The evaluation of the students for grade assignment will depend on a) the quality of the student’s oral presentation;
b) the students extent and depth of participation in the discussions of each and every seminar;
c) the completion of papers given as homework assignments. Attention is mandatory for all sessions.
No specific textbook will be assigned but the students will be sent to special Journals and books and are expected
to search relevant literature and visit references beyond those provided by the instructors and share their findings
with all in the class.
Instructors: Migeon, Moudrianakis
020.643 Viruses and Anti-Virals
Viral infections are a major health problem to the entire world. The human and economic cost to
society is tremendous; however, for many of these diseases no effective cures are available.
Viral infections like HIV/AIDS, hepatitis C, herpes, HPV, SARS, avian flu, west nile virus, dengue
not only affect or threaten people in the developing world but also in the most developed regions of
the planet. Currently, fewer than 30 antivirals have been approved by the FDA, most of which
specifically target HIV/AIDS. This course will discuss current strategies and approaches for the
development of new anti-virals using a molecular and thermodynamic point of view.
Instructors: Beemon, Freire
A graduate seminar course that will explore RNA from Its beginning in the primordial RNA world to its
present-day roles in gene regulation in bacteria, mammals, and viruses. Topics will include: The early
RNA world, Riboswitches, Ribozymes, evolution of protein synthesis, splicing, telomerase, RNA interference,
microRNAs, long non-coding RNAs, Viral non-coding RNAs, and RNA therapeutics.
Grad students only. Undergrads with permission of instructor.

protein synthesis (i.e., the "central dogma" of molecular biology) in molecular
detail, as well as how these processes are regulated and interrelated. There is
significant examination of molecular structure-function relationships, with
particular emphasis on RNA synthesis and processing and chromosomal
organization, nucleosome regulation and epigenetics. Modern and fundamental
experimental techniques and concepts are explored in detail. Students will learn
how to use some genome databases and bioinformatics tools available online to
improve their molecular biology research skills and knowledge. Readings are both
