Course Objectives

 

Upon completing the course, students will:

1.      Possess practical experience in many of the molecular biology techniques used in basic and applied research laboratories. 

2.      Be proficient in experimental design of molecular biological based questions.

3.      Be able to read and comprehend the current molecular biology literature.

 

Course Description

 

The course demonstrates the applications of molecular biology by involving the students in a real time research project.  The course employs a combined lecture/laboratory format.  Students will perform experiments using molecular biology techniques in the context of a muscle protein functionality study.  Students will identify and select a DNA sequence from the National Center for Biotechnology Information (NCBI), design oligonucleotide primers for PCR amplification of the gene, and clone the amplified gene fragment into an epitope-tagging expression vector in E. coli. Students will gain experience in protein analytical techniques by expressing the gene product encoded by the cloned DNA, purifying it by metal chelation affinity chromatography, and analyzing the expressed recombinant protein by polyacrylamide gel electrophoresis and western immunoblot techniques.  RT PCR analysis of isolated RNA will assess the expression of the muscle protein gene in various tissues.


 

 

Grading Criteria

 

The course will be graded on an A-E basis.  Individual student comprehension of the material will be assessed through seven homework assignments (70 %), weekly assessment of the lab notebook (10%), and an oral presentation on the last day of the course (20 %).A       90.0 - 100

B          80.0 - 89.9

C         70.0 - 79.9

D         60.0 - 69.9

E            0.0 - 59.9

 

Academic Integrity (Academic Misconduct)

 

Academic integrity is essential to maintaining an environment that fosters excellence in teaching, research, and other educational and scholarly activities.  Thus, The Ohio State University and the Committee on Academic Misconduct (COAM) expect that all students have read and understand the University’s Code of Student Conduct, and that all students will complete all academic and scholarly assignments with fairness and honesty.  Students must recognize that failure to follow the rules and guidelines established in the University’s Code of Student Conduct and this syllabus may constitute “Academic Misconduct.”

 

The Ohio State University’s Code of Student Conduct (Section 3335-23-04) defines academic misconduct as: “Any activity that tends to compromise the academic integrity of the University, or subvert the educational process.”  Examples of academic misconduct include (but are not limited to) plagiarism, collusion (unauthorized collaboration), copying the work of another student, and possession of unauthorized materials during an examination.  Ignorance of the University’s Code of Student Conduct is never considered an “excuse” for academic misconduct, so I recommend that you review the Code of Student Conduct and, specifically, the sections dealing with academic misconduct.

 

If we suspect that a student has committed academic misconduct in this course, we are obligated by University Rules to report our suspicions to the Committee on Academic Misconduct.  If COAM determines that a student has violated the University’s Code of Student Conduct (i.e., committed academic misconduct), the sanctions for the misconduct could include a failing grade in this course and suspension or dismissal from the University.

 

If you have any questions about the above policy or what constitutes academic misconduct in this course, please contact either Dr. Wick or Dr. Wang.

LABORATORY POLICIES

Safety

 

·        Complete the online safety training at http://info.med.yale.edu/caim/hhmi/public/ .

·        Precautions must be taken in the laboratory portion of the course to protect us from chemicals and biohazards and to protect our experiments from microbial contaminants and enzymes on human skin. 

·        Lab coats must be worn at all times.  If you do not have your own lab coat, one will be provided for you.

·        Safety glasses will be provided for everyone and should be worn at all times in the lab.

·        When using UV light, safety glasses impermeable to UV light must be worn.  A face shield is also recommended.

·        Many procedures will require the use of gloves to protect you or to protect your experiment.  When indicated in protocol or by instructor, gloves must be worn.

·        No food or drinks are allowed in the laboratory.

·        Extinguish open flames when finished.  Never leave an open flame unattended.

·        Bio-hazardous materials must be disposed of in biohazard containers.  Solid waste goes in the biohazard box located in the lab.  Petri dishes should be taped closed before disposal.  Liquid waste goes in the waste container provided to each group to be autoclaved after class.

·        Please notify instructor if you are pregnant.

 

General

·        You will be using some expensive equipment during the course.  Please be cautious when using all equipment.  If you are in doubt about the proper operation of a machine, ASK.

·        Each group will receive 2 – 3 micropipettes.  These are expensive.  Do not drop or abuse the micropipettes.

·        Everyone will share many of the reagents you will be using.  Please take care not to contaminate reagents.  Only fresh, sterile pipettes or pipette tips should be used to remove reagents.

·        At the end of each laboratory session, clean your glassware and leave it to dry in dish drainer.  Each group will have a box in which to store their things.  Replace all items in your box when finished.

·        Sanitize your bench top before and after working.

 

Lab Notebook

An up-to-date lab notebook is an essential part of good research.  As such, each student will be required to keep an up-to-date notebook which will be collected and graded each Friday.  The notebook will be graded for the following:

 

  1. Purpose and date of the experiment.
  2. Experimental design.
  3. ALL calculations (the notebook IS your scratch paper!!!).
  4. Observations
  5. Conclusions
